Magic · Yundun Trial Report -By Ye Dong
Write at the front ：
With the advent of the Internet era, more and more personal information is exposed on this big Internet. What can we do to protect our backyard from prying or infringement?
that Today we come See if Magic Cloud Shield can be our security guard!
I. Appearance: Yundun's packaging box is nothing special. It's just an ordinary hamburger structure. The opening damping is OK. Yundun looks a little like the car keys of some cars. It is small and weighs only 45g It is not burdensome to hold it in your hand, but because of its smooth body, ABS+PC It is made of the same material and does not have the shape design of sticking to the hand, so the hand feel is only average. The second one is a picture on the official website, which clearly shows all the details of the product. The handle of the switch is OK, and the rebound is simple. The USB interface below is of good workmanship. There will be no interface activity or unskillful plugging. Overall, the workmanship is good.
2、 Product main function
1） Security protection: privacy encryption, backup encryption
2） Password assistant: This function is very useful for people with many passwords and Ma Daha. Online games and bank card information can be saved
3） Backup: mobile terminal (may be available in the future PC ）Contacts, documents, photos, videos, etc
4） Fingerprint management: and Apple's touch ID The management is similar, but the minimum storage three There are only a few fingerprints, but they are enough. Because the grip is relatively fixed, you can usually input your thumbs (the third one can be left to the family leader zero ）
5） wireless U Disk: It is equivalent to expanding mobile phone capacity 16G (There will be other capacity versions in the future) 16G Apple, but friends with many songs and photos are very practical
3、 Endurance and efficiency
one ）Endurance: according to the official website: 920mAH/6h Support continuous operation in video mode six Hours; I feel that five There are still hours. If it is backed up once a week, it should be OK to recharge it once a month (because it has only been used for a few days, it cannot be verified)
2） Charging: official nominal three Hours, actually used 5V1A The charger of three About hours, as 920mAH The battery speed is still relatively slow, but the problem is that the heat is serious, a little hot.
IV, Product experience
Before the product arrived, I looked at the price（ 399RMB16G ）, thinking there will be a network cloud disk or wireless card wifi This function, but the actual measurement proves that I want more. When I unpacked it after I got it, the packaging box was pretty good. It was similar to the structure of ordinary mobile phone packaging boxes. The style was simple. Although the white plastic had no sense of class, it was not too bad. The workmanship was good. It can be seen from the interface, shell and data cable of the main body. The data cable adopts Android, which is flattering to users IOS The general style and quality are also good, but the wire is short. The instructions in the package are simple and clear.
Hardware 16G The capacity of two The times of transferring pictures are seventy-two Zhang（ 17.19MB ） fifty-two Seconds, fifty-three Zhang（ 47.94MB ） one hundred and twenty-nine Seconds. The speed is about 1MB About. Considering that incremental backup is possible, the speed is acceptable.
Then there is the largest slot point, which is also the purchase point of this product "fingerprint identification". It is not the same touch module and earplug as most mobile phones today ten A few years ago, it was usually in the high-end IBM T Series or DELL And HP's high-end business computers only have "swipe card" fingerprint recognition. Recently, we can see that the device using this solution is Samsung a few days ago S5 . Although S5 The recognition success rate of ten Notebooks will be improved a lot years ago, but 5S Of touch ID There is still a big gap between such click solutions. As for our leading role today, it's not as good as S5 , the actual measurement is about one hundred Secondary identification five Second to ten Times. (It should be lower than this... I spent a lot of time on fingerprint testing two Hours, it has already collapsed) This has greatly reduced the practicability of this function, and I entered the mobile phone APP Generally, the password is entered.
Finally, in the software part, I first said that I don't know what the manufacturer's strategy is, but I think I will buy this external device U Most disk devices should still be Apple users, but the update speed of Yundun on the Apple side will be much slower, whether it is a function (no one button Internet access, etc.) or UI Stability (capacity icon It can be pulled out a little), which is much worse than Android. Later, I used another Android machine as the test environment. But the one touch Internet access function is still unavailable (it should only be used 3G surf the internet, wifi Connect Yundun, but not at the same time. Of course, I think too much.) There are also some details. For example, when transferring pictures, there is only a progress bar. If you don't have time, you don't even know the percentage. The progress bar is very thin. I hope the manufacturer can optimize it slowly. Another two points: first, the entry of the password database is too complicated, and second, it is a very useful software. If the user's ease of use is not particularly good, then make a slightly better user guide
five ， Summarize the main selling points
Security: I can't test this for the time being, but in many Android clients, you can directly enter the interface after locking the screen without entering a password. In addition to the underlying problems of Android system, I really feel unreliable
Wireless USB flash disk: It can not occupy the body storage, especially Apple 16G It can store more photos, conveniently back up your own documents, videos and contacts. The speed is average but acceptable, and the standby time is enough for daily use.
Privacy: I think this is the best selling point of this product at present. The current network cloud disk is very developed. Baidu Cloud, Jinshan Express three hundred and sixty Cloud disks and Tencent micro disks, etc., but because they are stored in the server segment, in addition to small probability factors such as server downtime and virus damage, there are also some photos, files, business information, etc. that do not want to be seen by others or are not suitable for disclosure, which is more suitable for storage in this Yundun.
Under final positioning:
If you need a small (portable) personal privacy garden (you want to keep the last pure land of self or business privacy in this noisy Internet), this product will be very suitable for you.
Write at the end:
Good workmanship, privacy protection, second phone storage, but the lack of fingerprint identification, software optimization and so on make me feel that it should not be a product that can be mass produced, but more should be a product in alpha or public beta stage
Last Last:
I hope that the current intelligent hardware manufacturers can solve problems before the interview, rather than leaving all problems to the market, which is not only irresponsible for customers, but also irresponsible for products and their own companies!
