First of all, let’s talk about the current demand. After all, there must be a motive for doing anything. At present, the family needs to focus on:
1. For daily BT and PT downloads, although the USB disk can be mounted on the route, the access speed is worrying. In addition, the capacity of the USB disk is too small to mount a mobile hard disk, which is not convenient to place on the table, and the power consumption of the computer download is even more touching.
2. Home Multimedia Service Center. There are more and more mobile devices in the home now. A small home server is indispensable for browsing the retained photos on IPAD, watching high-definition movies on TV, listening to the collected classical music on mobile phones, and for centralized control and convenient sharing.
3. I bought a mobile phone in the early years and imagined that 64G of space was completely enough. As a result, now I find that the space is really too small to meet the daily use. In order to migrate the data in the mobile phone completely and safely, it is too uneconomical to spend money to expand icloud, and a convenient synchronous backup tool is needed to be available at any time.
4. The photos, useful data and relevant documents over the years need to be backed up and archived in a unified way so that they can be retrieved more conveniently anytime and anywhere. The Internet disk is becoming more and more unreliable, so consider private cloud.
The basic needs are concentrated on the above daily use, and the price of the entry NAS for household use has generally come down now. The expensive one is hard disk instead. Recently, the dog owner started the activity with two disks at a low price. It just happened to be able to put the matter on the agenda and kept watching until he saw a new TS-212P3 two-disk machine installed by WISCO two days ago. The size is also appropriate, the appearance is quite small, and it is convenient to place the desktop. Finally, he decided to try water. Previously, Qunhui and Weiunicom had been entangled for a long time. Qunhui focused on the quality of ease-of-use software, and Weiunicom focused on data security and professional functions, and both had their own focuses in the household and commercial fields. In fact, the two brands can fully meet the current household needs. For me, it was nothing more than the difference in operating convenience and UI aesthetics. In addition, considering the size of the desktop, the decision was finally made to join Weiunicom.
Out of the box:
Although I bought an entry-level NAS, after all, data safety was the first thing. I bought a UPS by the way to be on the safe side. I have to say that the price of this UPS has increased a lot. It was only over 300 two years ago, but now it is more than 500 directly. The fake UPS is not considered. This APC UPS was recommended by many friends in the industry, so I was relieved to enter. If I have a hard disk, I bought Seagate’s Cool Wolf 2T*2 NAS special disk this time.
Wei unicom’s packaging is still very simple, just a yellow corrugated box with a LOGO printed on it, which simply indicates the selling points of the following functions.
The profile is also the same. It is very concise, leaves a lot of white space, has no jumbled introduction, and has only two rows of bilingual functional explanations.
The shockproof packaging is well done, and the ” small white” is seen as soon as it is opened. It is indeed very small, and what is needed is this effect.
Accessories include: warranty card, certificate of approval, power adapter, SATA data cable, network cable.
The power supply is made by Delta, with output of 12V-5.417A and rated power of 65W.
Gigabit specification, super class 5 unshielded network cable.
SATA transmission line, which will be used when installing the second hard disk.
Wei unicom TS-212P3 continues the appearance of the previous generation TS-212P. the model is still very small and light, with rounded corners and simple white. it matches with my white computer desk and white mainframe, which is one of the reasons why I chose it.
From top to bottom, the front is: one-button backup button, USB 3.0 interface, all-in-one status indicator, HDD1, HDD2 work indicator, LAN network signal lamp, and on/off button.
Fan outlets, two USB 2.0 interfaces, RJ45 network cable jacks, reset holes, power supply interfaces and Kensington safety lock holes are distributed at the tail.
At the bottom, four shock-absorbing and skid-proof foot pads can be seen, and corresponding model numbers and certification marks are pasted in the middle.
Except for the active cooling fan at the tail, the passive cooling hole is at the bottom. Generally, the power consumption of the machine at this position is not much higher, and the heating value is not too large. It should be no problem.
The next step is to disassemble and assemble, unscrew the two fixing screws at the tail, and be careful not to screw the fixing screws of the fan.
Push the housing horizontally forward to open the NAS.
Inside the NAS, the upper layer is a 3.5-inch hard disk mounting position, and the lower layer hides the PCB board.
Select Seagate disk that has been used all the time. Cool Wolf series is also Seagate’s series disk specially designed for NAS. It is optimized for NAS and supports 7×24 uninterrupted work. The disk speed is 5900rpm, and 7200 is free. It is hard to read and write. After all, unlike computers, it is quiet and stable at work.
There is no tool-free hard disk bracket for the two disk positions, which can only be fixed with screws. I found that two of the attached screws are slightly shorter in length. I didn’t pay much attention to them during installation. I forced a wave of tightening and found that the screws were slippery. However, I found two screws to fix them. When installing, I noticed that I didn’t pay much attention to which hole these two short screws were used to fix.
After one disk is fixed, the second disk is clamped with the buckle shown in the figure above, which can prevent resonance between hard disks.
After installing the last disk, fix the screws and insert the SATA cable of the second disk. So Easy.
Five work indicators, buzzers and other components, other components hidden under the hard disk bracket, need a special screwdriver to unscrew, I did not open it.
Don’t worry about putting on the cover first. In order to prevent the problem from being disassembled and assembled for the second time, it is better to test the machine with electricity and install the system first. It is not too late to close the cover after normal use.
APC’s BK650 UPS is the most commonly used UPS for NAS at present. It has a special NAS data communication interface. When the power is cut off, it will automatically notify NAS that the power is cut off. It is time to stop working to prevent hard disk damage and data loss. Here, I have to complain. I don’t know whether it is my RP problem or whether the UPS found that the battery inside was shaking in my hand after receiving it. The kind that is very strong actually told me that it is normal after asking customer service. I was going to return the product, but I think that there is only one battery in the product, which should not cause any serious problems. It may just be that it is not fixed properly, and I will not touch it when I use it normally. In addition, the product is too stupid and heavy, and it wastes time, too much trouble and patience.
For the first time, there are two ways to initialize the machine, one is cloud initialization, and the other is local initialization, which is convenient for personal drawing and directly cloud initialization.
Cloud Initialization Direct Access:https://start.qnap.com/cn/This official page of China Unicom will be fine. If your NAS is connected to the network normally, it can be scanned directly. Then you can go directly to the next step. There are not many places to set up.
Note this place, need to set the name of the machine, this name is not the login user name, the user name is admin by default, this cannot be changed, password or something to set up.
Firmware installation, it is recommended to download the firmware for local installation, and it is also recommended to install version 4.2 instead of upgrading to the latest version, because some software in the new version is out of date and needs to be done again, which is very troublesome and experienced personally.
For hard disk group RAID, I suggest either not to group at all and choose JBOD mode or RIAD1, because only two disks are supported. This is the RIAD mode with the best data security of the two disks at present. It gives consideration to both performance and data security. The disadvantage is that you have to sacrifice 1/2 of the disk capacity, two 2T disks, and only 2T space is available for RIAD1 after group, not counting the space occupied by the system itself. However, for data security, what is the significance of buying NAS otherwise. Other options default.
The system will restart automatically after RAID is set up, just wait for the second reading to complete.
While local initialization requires downloading the software Qfinder Pro, the links will not be attached one by one. After the installation is completed, the software will also automatically prompt you for uninitialized NAS. Just follow the steps and it is not complicated.
When you see this interface, it proves that everything has been completed and you can log in to the system with the set password.
This is the interface after logging in. Of course, this is the interface after I have downloaded some commonly used software. The corresponding application software needs to be downloaded in App Center.
The console is divided into four sections according to system, authority, network & file service, application service, etc. 90% of the settings are concentrated here.
Since I bought UPS, the first thing is to set it up first. After connecting the signal wire attached to UPS to NAS, I will receive a prompt in the main interface of NAS. Click to open the setting of external equipment and jump to the corresponding setting interface, or set it through console-system-external equipment. The initial default is to shut down the system in 5 minutes. In order to save electricity and prolong the service life of UPS, it is changed to 2 minutes. In fact, 1 minute is fine. If you have multiple NAS that need to share UPS, you can activate the following network uninterruptible power supply server and enter the corresponding IP address.
User rights settings:
User permissions here are created according to requirements, and corresponding information such as user’s head portrait, name, group, telephone number and the like can be set separately to distinguish. folder permissions can be set here or set separately afterwards, and application permissions can also be set. since I am a household, all folder read and write permissions are turned on. if there are some things I don’t want other people in the family to see, I can give a user corresponding read and write permissions for a folder separately. this is very flexible and can be set according to my own needs.
Sharing folder permissions can set which folders are shared with which people and which permissions are given to them. There is nothing to say.
Disk quotas can limit the amount of capacity used by different users on NAS. It is not necessary for home use. It is still meaningful for companies to use it. Of course, different sizes of capacity can be divided for each user.
In the houses decorated in earlier years, the wiring was not particularly reasonable, and there were no reserved network ports in many places. if this happens, USB—WIFI can be used. I put the routing and NAS together, so I don’t need this function.
DDNS and myQNAPcloud:
It is believed that many routing partners are familiar with DDNS, and they will also use it in remote routing. Similarly, if you want remote NAS, you must also set up DDNS, so as to facilitate the official launch of myQNAPcloud service by China Unicom, which simplifies the operation and can be passed after simple setup.https://qlink.to(Device Name) To connect to your NAS remotely, DDNS, port forwarding etc. You can configure your router automatically with one click in myQNAPcloud settings. Of course, the premise is that your router must support UPnP. Now basically all routers also have this function, which is basically no problem. Of course, in order to be more stable and multi-insured, you can register a free domain name by yourself, and it is also possible to do it simply.
Take peanut shell as an example. For other domain names, you must first confirm that you have public network IP. If you do not have public network IP, you need to use intranet penetration. Peanut shell also provides it. There are many specific details, so it is not necessary to repeat them. It is easy to apply for a free shell domain name. Then you can select network access-DDNS service in QNAP console. Just fill in the above figure according to the steps. This step can also be completed in the router. Currently, there are basically dynamic DNS(DDNS) options in the intelligent router.
Also bind you to apply for peanut shell domain name, here simply say the following principle, because the public network IP is changed, not fixed, every time you surf the Internet, the operator will assign you a temporary IP, and DDNS is used to map this changed temporary IP to a fixed domain name resolution service, which corresponds to the domain name, so that you can access this IP through this domain name, no matter how this IP changes, it will not affect the access of the domain name.
Through the above domain name, you can now access your home intranet remotely. You must also tell the router which device below the network access request is forwarded to, for example, my intranet IP, NAS is fixed IP 192.168.2.102(NAS IP is set to fixed, otherwise the route cannot be connected after IP redistribution), and computer IP is 192.168.2.101. So now I’m looking for NAS, server IP. Fill in the internal IP address of NAS here: 192.168.2.102. The default for internal port QNAP is 8080. Here I change to 8882. Fill in as many as you want. The external port and internal port are set to be the same. The protocol can be TCP or UDP or both. Save and restart the route after filling in. Now you can access NAS remotely through domain name and port number. For example, peanut shell’s: XXXX.imwork.net:8882 (8882 changed to your NAS port number). Have you seen the familiar login interface again, so far, remote access to NAS has been completed.
To make folders (drives) on NAS appear in my computer for easy and quick access, there are three ways: iSCSI mount, windows mapping network drive, Qfinder Pro one-key mapping.
Since there is one-key mapping, why choose the troublesome method? Directly through the Qfinder Pro, tools-mapping network drive is good, if you are other computers in the LAN, there is no download client, the method is also very simple:
Select my computer-computer-map network drive-browse-select the folder to add-ok, iSCSI will not go into details, and it is also very simple for interested self-carers.
File Station file manager:
File Station, whose function is a bit like RE file manager, can edit, copy and paste files, restore snapshots, delete files, and even mount files remotely through NFS/SMB. What I use here is mainly sharing. In the past, I used to share files mainly through network disks. Links often fail. Now with NAS, these are no longer worrying problems. QNAP’s sharing function is still very useful.
Right-click file sharing, you can choose email sharing, community website sharing (only Sina Weibo and everyone are supported in China, and all others are foreign social platforms), sharing links, and sharing to other NAS users. take sharing links as an example, you can choose the validity period of sharing, encryption or not. users of both internal and external networks can download the shared files, and the money of Baidu internet disk members is saved.
The page opened after sharing looks like this.
All shared links can be tracked in File Station sub-option: Sharing Link Management. You can see the information of the sharer, sharing duration, encryption or not, and you can stop this link at any time so that others can no longer download it.
Mobile Qfile file manager:
For the first time, the mobile phone Qfile will automatically search NAS if it is used in a local area network, and it is good to enter the username and password connection. if it is used remotely from the external network, it is good to enter the myQNAPcloud name of China Unicom, or log in with peanut shells. there is no problem. 90% of File Station functions can be basically realized on Qfile, and common editing functions and sharing functions are all available. Including stopping sharing, all can be operated by the mobile phone. Qfile can automatically upload pictures, videos and other files on the mobile phone to NAS. in the setting, an automatic upload strategy can be set. I chose to upload only in WIFI state, so that some photos normally taken can be automatically returned to NAS upon returning home and edited and viewed directly in NAS.
Entertainment three swordsmen (Photo Station, Music Station, Video Station)
Photo Station You can think of it as a QQ photo album. It has the function of a photo wall. All synchronized photos will be displayed in this way.
You can also add, delete, copy, paste, share, download, create photo albums, multi-latitude sort, filter, slide show and other operations in the gallery management.
Open a photo. This is the photo browsing mode. When I use it on a normal computer, I basically browse it locally due to the disk mapping. The operation is also done locally, so this one brought by NAS is not used much.
Music Station has functions similar to QQ music. The initial interface has two options: spotlight mode and management mode. This is spotlight mode and you can see large classification options.
Under the management mode, it can also add, delete, share music, create playlists, etc. In addition, it supports streaming to other playback devices. Unfortunately, compared with chicken ribs, it only supports Mp3 format. Usually, computers use other music software to listen to songs. This function is not used much, and music is only used for backup.
The interface opened by Video Station is somewhat similar to Photo Station. All videos are also displayed in the form of thumbnails. All videos can also be added, deleted, downloaded and shared.
Video Station cannot be played directly in NAS. QVHelper needs to be downloaded and played on the computer side or can be played with the help of a third-party player. QVHelper has been installed unsuccessfully for some reason. The same is still true for two computers. In fact, apart from occasional use of Photo Station, the other two of the three softwares are not normally used, and are directly replaced by other softwares on the computer side, especially for watching movies.
On the handset side: QPhoto, QMusic, QVideo
In fact, you should be able to guess by looking at the name. this is the APP end of the phones of Photo Station, Music Station and Video Station.
QPhoto on the mobile phone side is still very practical. when you want to browse photos, you usually use QPhoto to browse directly. there are basic common functions. now I directly synchronize all photos in the mobile phone to NAS, and then empty the local photos to save the space of the mobile phone. when you need to browse photos, you can directly open the application, which is no different from the local photo album. you can also retrieve the local photos at any time, and you can also directly share them with one key. The commonly used functions are quite complete, but there is no photo beautification function. If you want to fix the picture, you can only borrow the third-party APP. In addition, there is a good function, QPhoto can be transmitted as you take it. Whether it is a video or a photo, it will be directly stored on the NAS after the photo is taken. The icon of the camera and video camera can be seen on the photo sharing page above. This function is quite practical in some scenes.
In addition, photos can be browsed in 360 panorama, but this function is of little practical use. VR mode can also be turned on when browsing in panorama. This is far from practical. The photo editing function of QPhoto is very few and can only be adjusted by simple rotation.
Like Music Station on APP, QMusic still cannot solve the problem that no other formats can be played except Mp3 format. I was excited to see that QMusic setup has an online real-time format conversion function. as a result, I found that my version is too low and cannot be upgraded to a higher version. this should be related to NAS model. I have an inexplicable sense of discrimination in my heart, and the function is slightly less. In addition to the normal functions of playing and streaming to other devices, the sharing function has been removed and cannot be directly shared here. However, the music I put in NAS is some classic music or some music in lossless format. If you want to play it, you can download it directly to the local and play it with a third-party music player.
QVideo is exactly the same as the original player. The original player provides limited functions, but it can also be used normally. The commonly used functions of sharing, downloading and streaming still exist. There is no pressure to play 4K movie sources, there is no Catton when dragging at will, and online subtitles can be added. However, I would like to talk about Amway’s other apple player, which is the most powerful and best-used of all the apple players I have used at present-—nplayer.
In the previous protocol chart, basically all the current mainstream protocols are supported, and cloud seeding is not a problem, which shows its powerful functions.
After using SMB protocol and adding NAS, you can log in directly with one click for subsequent use. Video playback provides a wealth of functions. Even double-speed playback is available, which is completely enough for daily use. It is also free of Catton. In addition, it supports all current mainstream music formats. It is not impossible to listen to songs with it, and it is no problem to browse pictures. However, I still use video playback most.
NAS mobile monitoring software (Qmanager):
Qmanager is a monitoring and management software for mobile phones. It is very convenient to remotely manage NAS especially when you are not at home. You can see the running status of the system in real time, and can remotely shut down, set permissions, backup, etc.
Qsync synchronization software:
This software is quite practical for me. It is inevitable that I will install a Qsync synchronization software on the company’s computer when I have not finished my work. Using myQNAPcloud, peanut shells can also be used to log in NAS remotely to synchronize the unfinished files directly to the NAS in my home. When I get home, I can open the computer and see the files, which is convenient to continue the operation.
This is the interface of Qsync in QTS system. the administrator can set which users have the right to use Qsync here, assign different folders to different users, or share a team folder, so that the team members can work together more directly. as an administrator, the administrator can also view the synchronization trend and equipment connection status of all Qsync in real time. of course, it is basically unnecessary for home use. the functions I use also open up the simultaneous use of company and home.
This is the Qsync software on the computer side, which can be manually clicked to synchronize or the software can be automatically synchronized. the synchronization function on the mobile phone side is already included in the Qfile, and the Qsync folder can be seen by opening the Qfile.
The process of Qsync synchronization, in short, requires a synchronization folder corresponding to NAS on the computer side. This can be set by ourselves. After setting, we can directly drag any file on the computer into this folder, or right-click the file to be synchronized and select Copy/Move to the synchronization folder. Qsync will automatically synchronize the file under the folder to NAS after detecting the data change in the folder, for the same reason. When new data is imported into the synchronization folder in NAS, it will be synchronized back to the computer side. The folder used for synchronization will have a synchronization identifier, which is convenient to distinguish.
BT, PT download station:
I believe it goes without saying that one of the important functions of buying NAS is to download it 7×24 hours with low power consumption. It is convenient to use it to raise a number. That’s exactly what I did.
The download software provided by China Unicom is called Download Station. The above picture is a screenshot of the English interface. It can be set to Chinese. The download speed is tested. The download speed of 50 megabytes of China Unicom optical fiber can reach almost 7MB/s at the fastest speed. It can be full speed anyway. In fact, this is of no reference significance. This depends on the seed. It is possible that the seed quality is not good for dozens of K. The Download Station provided by China Unicom supports the download of Http, FTP, BT and some PT sites, which can basically meet the daily use. In addition, there is another recommendation for downloading software commonly used by individuals: Transmission. I believe everyone is familiar with it. unfortunately, the 4.3 version of the software has not been found in the stores at present, and officials have been consulted. this version of the software cannot be downgraded. therefore, it is very difficult to find a usable version of 2.93 after all kinds of troubles and FQ.
This is the interface after localization, which is widely used by individuals. Therefore, it is recommended that PT generally use it. It is worth mentioning here that when PT downloads, remember to cancel the DHT option, otherwise there is a risk of being blocked, including the Download Station. In addition, if Download Station downloads some BT resources without speed, IPS may block the port, and it should be enough to change the port.
Qget on mobile phone:
This is the mobile phone terminal corresponding to the Download Station in QTS. Whether it is the Download Station in QTS or the Qget on the mobile phone terminal, it is good for you to regard it as a simple download tool. As for searching resources, it is too unreliable. I simply tested it. Some popular movies in common use are not found at all, and the searched resources are all download links without any marked information, and the downloaded resources are not the resources you are looking for. Therefore, it is good to look at this search function. After all, there are not many resources in the download software.
Qget this software can’t be found in apple stores in China or the United States through the two-dimensional code given by the government. it manually searched for a QGet Remote or a paid version. finally, it solved the problem by itself. the above figure is the interface for searching and found an old resource. the information searched out is shown in the figure below. the Download Station, too, picked the resource with the highest heat and downloaded it. The result is fifty shades of grey or English version, so if there is a download link, it will be downloaded directly through the ” Enter URL” option in APP. Several other functions can be ignored. Transmission has no IOS client and can only be remote from the Web without affecting its use.
Before this, when Weiunicom cooperated with Thunderbolt, it got Thunderbolt’s authorization. After that, there was no cooperation. The store also took off the corresponding service. Now Thunderbolt is useless, including Baidu Cloud. However, Baidu Cloud can now be downloaded synchronously through a third party: Cloud Moving. This software is charged, so I gave up. If Thunderbolt must be used for remote downloading, it can be implemented through Docker Remote Thunderbolt. Due to the entry-level configuration of TS-212P3 that I have at present, including virtual machines, the items that need to be configured will not be disturbed. If the subsequent demand is strong, I may consider upgrading again and disturbing again at that time.
There is a 720P xiaoxing at home. he is not at home normally. he can look at his two cats at home, thinking that he can save a copy of the video on NAS, and can view it remotely when he is in the company. the result has been bothering for a long time. it is found that this survey station software in QTS does not support this type of camera. if it is convenient for the owner of the store or other people who have video monitoring needs, he can do it. The functions provided by this software are roughly: multi-camera split-screen monitoring, motion detection alarm, custom recording time, resolution, image quality adjustment, etc. Since it is not supported, I do not know how to experience it in actual use.
Let’s talk about the snapshot function alone. To open a snapshot, you need to set it up first and allocate LUN space to it for storage. Snapshots can support permanent storage for up to 12 months. For home use, I think 7 days is enough. If there is too much, it requires more disk space, and its own capacity is not large. It is not necessary. If it is used by a company, it is still necessary. Of course, you can also select a disk with a larger capacity. Snapshots are very helpful for tracking historical data. They can be traced back to any time node to deal with some unexpected situations, hanging disks, etc. It is still very useful.
The function of one-key backup is actually quite convenient to use. Under the condition of not turning on the computer, plug in an external U disk or other storage device. Click the one-key backup button, NAS will automatically synchronize the files in the external storage device, and can confirm whether synchronization is completed through the status indicator. If only a camera SD card slot can be added, then every time a photo is taken, plug in the SD card directly, synchronization is good, and then turn on the mobile phone to view it.
Transmission speed test:
Before the test, let’s talk about the test environment. At present, the network used is Unicom 50M optical fiber, the router is Fijian K3, the network cable is super class 5 unshielded, and the wired network card is onboard Killer E2400
Card, take reading and writing a 4K movie as an example:
The speed of copying files from NAS to the local area network is basically maintained at about 110MB/s, and the speed can be seen from the peak diagram that the speed is relatively stable, basically running up to the upper limit of gigabit LAN.
From desktop copying files to NAS, this peak diagram is a bit interesting. The speed is relatively slow in the initial stage. After climbing continuously, it gradually tends to be stable. Most of the time, it is maintained at about 100MB/s, which is slower than the reading speed, and it is almost full of gigabytes.
LAN, mobile phone 5G upload speed is about 15.37MB/s, download speed is about 17.24MB/s.
The upload speed of mobile phone 2.4G is about 6.15MB/s and the download speed is about 7.23mb/s.
Power consumption, noise and heat dissipation performance test:
The power consumption of NAS during normal operation is about 14.1W W. It seems that the power consumption of NAS with two disks is really low. Even if the NAS is not turned off for a year or two, it will not feel distressed.
Before the test, the measured ambient noise is about 40.5dBA. The noise meter is placed against NAS, and the measured noise is about 44.3dBA. It can be seen that the actual noise is very small, and it is no problem to use the table top. If it is placed in a place like the bedroom, it will not affect sleeping and the sound is very low.
The temperature test data is for reference only. The ambient temperature is 26.1 ℃, the enclosure temperature is about 31.5 ℃ when NAS works normally, and the temperature of the system and the disk is about 40 ℃. I think it is probably due to the plastic enclosure. If it is a metal enclosure, the heat dissipation effect will definitely be much better, but this temperature is also the normal temperature.
In case of personal dissatisfaction, the status indicator of TS-212P3 is too eye-catching, especially if it is placed on the desktop, it will involuntarily affect the line of sight. Personally, I suggest that a baffle or the like can be designed, or the user can choose whether to turn on the indicator or not, and NAS without the indicator will not affect the use.
TS-212P3 is a very small NAS, which does not take up too much desktop space when placed on the desktop. It is white and fits well with other surrounding hardware.
Finally, to sum up, the NAS of TS-212P3 of China Unicom can be summarized in one sentence: although TS-212P3 is small and full of organs, as far as I am concerned, what I value is its small size and efficiency, the entry-level configuration price, the cost-performance ratio is not bad, and the functions are complete. basically at this stage, my demands have been met. apart from a little regret in BT download, the others are not bad, and I also expect China Unicom to introduce more and better apps and the like in software.
