In the unit writing materials copy files, always use U disk, so nothing in the pocket there are always 2,3 units sent 8GU disk exists. Some of my colleagues will borrow from me because they do not use USB flash drives at ordinary times. If you do not borrow well, borrow some materials for fear of leaking (you may have guessed it here, yes, yes, I am Lei Feng). Sometimes I neglected where the U disk was, and they saw it and used it directly. Several times, they took my full sister and coughed....a USB flash drive full of confidential information. It scared me. Some leaders demanded the best confidentiality. They really couldn't be seen by everyone. what! A few years ago in South Korea bought ZALMAN's 2.5-inch hard disk box, hardware encryption function is to force, but this play should be after all the hard disk box, with inconvenience, so sprouted want to buy an encrypted U disk impulse.
Want to buy a U disk request is to decrypt the convenience, the computer to install a software decryption even if, because I always use a U disk to insert a variety of different computers, one by one to open the software is also more strenuous. So decryption is done on the U disk. Then the interface has to be USB3.0, after all, it is now standard on the U disk. The size of 32G is enough, and there is no use for more. If you have a read-only feature, it would be best, so that you can also prevent the insertion of a U disk virus on public computers. Fingerprint decryption U disk even if, had contact with several brands, workmanship is more cottage, writing USB3.0, speed is slower than 2.0. With the use of fingerprint recognition bits, the wearer can't recognize the fingerprint and hangs. And colleagues don't have my fingerprints, and sometimes it's not easy to share files. So find a find to find a U disk Kingston DataTravler 2000.
No matter if it is appearance or practicality, it will poison me, and the evaluation will be quite good. But looking at the price, it's too unfriendly! This can't be fun to play! 32G's in a treasure unexpectedly wants 999 yuan! The United States and Asia will also have to spend 119.99 US dollars, and it will cost about 900 yuan. Big sister's bedroom is so expensive? No, I mean to use such expensive things to save files? Continuing to find several similar ones, such as the Apricorn Aegis Secure series, etc., the prices are all too unfriendly. The principle of this U disk is basically the same, that is, U disk built-in encryption chip and buttons, there is a small battery, used to add and unlock the entire U disk. At this time, I saw that Aunt had pushed a new ship's padlock 3, with three anti-processing, upgraded from USB 2.0 of PadLock 2 to USB 3.0 transmission, supporting 256BIT AES encryption function, and authorized development of ClevX LLC. I immediately went to a certain east and a certain treasure. However, it was discovered that foreign countries have just been listed. There is no domestic market. Only the official website has relevant information. However, the United States and Asia have only $56.99! Baidu, Google's evaluation did not find any Chinese or English, and there are no practical things for the American and Asian reviewers, nor do they know what the specific measurements are. In contrast, this price is too friendly. Regardless of whether it is measured, buy it first! Immediately bought a friend to buy one.
Unpacking:
In fact, the basic appearance is similar to PadLock 2. The color is slightly lighter. The key is a lock/unlock key and 5 number keys, the rest is a red lock light, a green unlock light and a blue status light. The text on the back changed from the pirate ship's official website to PADLOCK 3. I feel very delicate workmanship, the body is rubber material, all the white text of the buttons are rubber raised. However, I estimate that it will take a long time and this rubber is basically worn out. Written on the above five-year warranty, but in foreign countries to buy a U disk ship can not guarantee the domestic I really do not know, but there is no invoice. There are friends who know about the warranty issues in the country. I have trouble telling me, thank you.
The way to remove it is to cut, cut, and clip, with a quick guide in six languages ​​(that is, no Chinese). However, from my lame English level, we understand how to use it basically. Then detailed instructions are downloaded from the official website, but they are all in English.
Take the first impression of this thing, a little big, about 8.6X2.7X1.5CM, weight about 15g. If the two USB ports on the computer are too close to each other, plug it in. The second port is a waste port and there is no space for plugging in. In this regard, Kingston's DT2000 will do more slender.
From the feel of the button, it is judged by the feel of the micro switch that life does not know how long it has been. However, the rubber shell I found was not sticky with the inside, although I didn't want to dismantle it, but if I use a special force, it should be able to pull off the whole rubber jacket. When you first arrived, you did not set any password. You can use it by plugging it into your computer.
On the chip wizard, it is correct to view USB 3.0. The main control is the group connection. (Say, the master of such hard encrypted U-disks seems to be group-linked).
The U disk's large file read and write speeds are fairly stable. Under USB2.0, the writing speed is about 36Mb/s, and the reading speed is about 40Mb/s. USB3.0 write speed is 46Mb/s, and read speed is about 80Mb/s (The longer the read time is, the slower the speed will be, and the time will drop to about 60Mb/s. Know why). I use a 3GB video file test. This speed I used to be quite satisfactory, after all, is a 32G U disk, usually also installed some fragmented files, rarely copy a large file. And it is also undergoing encryption and decryption processing, so the read and write speed will certainly not be too high.
Write and read under USB2.0.
Write and read under USB 3.0.
The test writing of ATTO and CDM under USB3.0 is probably 50Mb/s, and the reading is 138Mb/s.
Next is the highlight, oh, u disk password lock function! This U disk comes with a quick guide only to say how to set the User password, and I went to the official website to download the detailed instructions to write, you can also set a higher privilege Admin password. And can set Admin read/write and User read/write mode. Admin password and User password can be modified at will after unlocking with the original password. However, when the Admin password is unlocked, the User password will be cleared, which means that if you do not know the User password, you can use the Admin password to modify the User password. This feature I think is still more intimate, after all, if the user really forget the password changed, you can also have an Admin password to rescue. If the two passwords are all forgotten, there is also a function to restore the factory, but the cost is that the password, settings, and data in the U disk are all cleared and cannot be restored. After the Admin read-only mode is set, either the Admin password or the User password is unlocked, and the U disk will be read-only. After the User read-only mode is set, the user's password is unlocked and read-only. After the Admin password is unlocked, the read-write mode is still enabled. This feature I think is particularly good, so that when borrowing someone to see some files, just tell him the User password is not afraid he will accidentally delete the U disk files, and they can use the Admin password to read and write . When the U disk is unlocked, it can be powered by an internal battery or plugged into a computer. The unlocked U disk is the same as an ordinary U disk, and it can be inserted wherever it can be identified. After the U disk is safely deleted, the U disk will automatically lock, and then you will need to enter the password again to unlock.
The anti-hacking function is also good, after the password is wrong 5 times, U disk will lock 2 minutes can not be used. Then enter the wrong 5 times (to this cumulative error 10 times), lock 12 hours. Error 5 times (accumulated 15 times), locked for 2 minutes. Error 5 times (accumulated 20 times), U disk will automatically restore factory settings, clear all passwords, settings, files.
Because the instructions are in English, even if the above links are downloaded, they may not be able to understand them. Therefore, I will use the spirit of Comrade Lei Feng to translate the main features of the manual in English that I am not very accommodating. a bit. Some of the original descriptions were marked incorrectly or unmarked, and I have also corrected the actual functional tests. Is also to facilitate everyone to better understand this U disk!
In general, the cost-effectiveness of this U disk is still quite high. The domestic thieves official website has already had relevant information. It seems that the date of listing is just around the corner. Looking forward to the domestic listing price will be as kind as the United States and Asia. The main advantages and disadvantages I simply list are as follows:
advantage:
1. Plus unlock can be completed on the U disk, do not require any computer operation. After unlocking, it can be used in any place where U disk can be recognized. It can be used on mobile phones and tablets.
2. At the same time of strong confidentiality, read-only mode can be set to facilitate everyone's use under some working environment.
3. Although the characteristics of the three defenses are not completely waterproof, they are definitely enough to deal with all the conditions that a normal office worker can encounter in daily life.
Disadvantages:
1. The original double-level permission is a very convenient function, but after the Admin password is unlocked, the User password will be automatically cleared no matter what, and you need to set the User password again, which is a bit cumbersome.
2. The volume is a bit large, obviously can be done relatively small, why do so much, after my home laptop, desktop plug it, a cable can not be inserted, a waste of a USB port.
3. The speed of reading and writing is normal, but this price, as well as encryption, I also believe it.
4. There is no function such as the Kingston DT 2000 which is inserted on a computer for 15 minutes without data read/write. Sometimes if it runs out on a computer and forgets to pull it off, people still can still see the files inside, but looking back at the price, I still believe it.
The article is written and written for one day, and the translation and writing in the middle also takes a lot of effort.
