A few days ago, I found a lot of U-disks, just two days ago to see an original write with SSD as a mobile hard drive, catch up with the hands of M.2 hard drive, but also buy a box to make a mobile hard drive, by the way these are measured speed , simply comment on two sentences. This evaluation is simply to take a movie file to do the reading and writing, this article is not black and white, no use of software or anything, not so accurate, not so accurate, especially like the special study do not spray
Saying that the poor are playing with cars and playing hard, playing with computers. . . You have to play these things
Let's talk about the items to be evaluated first
128MB Patriot U disk (like flash memory) bought in 2004, USB1.0, is still fast in similar products, age is too long, no link
2, SanDisk cool bean generation 16GB, USB2.0, easy to carry, especially on the USB car songs
3, Apacer Apacer, 16GB, USB2.0, no features, push and pull the head, push and pull cards tight. The above U disk is 2.0 and 1.0, followed by 3.0
4, SanDisk Extreme high-speed OTG64GB, USB3.0, just the size, can be used on computers and Android phones, yes, is the bayonet is too loose, with Ma Rong's waistband like
5, SanDisk cool bean second generation 32GB, USB3.0, the same easy to carry, speed, and is how your hat so loose, worse than a generation, hey. Bi Ma Rong's waist is still loose
6, SanDisk CZ48, 16GB, USB3.0, nothing features, push-pull head, can not help, a little tighter than the waistband. Once I wanted to pull it naked, I didn't succeed. Who knows how to pull it, you can reply to me, thank you very much.
7, SanDisk CZ80, 32GB, USB3.0, long head, push-pull head, to be honest really do not like push-pull head, inserted into the loose, and my heart is always not the end
8, Kingston-DT 100G3 32GB, retractable cap, this plug is very real, but the speed is very general, USB3.0 seen the slowest
9, Kingston DTSE9 G2, 128GB, USB3.0, all-metal, high value, with a large ring, with a convenient, easy key, convenient, speed
10, Kingston DTmirco 64GB, USB3.1, all metal, with a small ring, with a convenient, convenient key, convenient speed
11, Seagate 2TB mobile hard drive, USB3.0 interface
12. Transcend-MTS400-M.2-2242-256GB
13, SanDisk-X300-M.2-2280-512GB, did not find x300, use x400 link to make do
14, SSD Kingston V300-240GB
15, SSD Samsung 850PRO-256GB
16, SSD-intel-730-480GB
17, Jinsheng, m.2 mobile hard disk box
18, orico, sata interface mobile hard disk box - two
19, desktop internal friendship, intel535-240GB, Samsung 850EVO-256GB, Western Digital black disk 2TB
20, and turned out a Toshiba éš¼ 2 generation 64G, 14 years of the disk, really good disk
Below to start mapping
Put two pictures first
Copy file speed started
Using a 2.79GB movie. Of course, not big sisters
The figure above shows the internal mechanical hard disk of the desktop grilling data to the SSD. The speed of the initial part has not been captured, and almost a high speed and uniform speed have been grasped.
Pictured above is the speed of the Samsung 850evo and the intel530 baking each other, very uniform, and soon, grab a picture, D drive is intel
The above picture is the writing and reading of CZ48. The two small figures are written, the next two small pictures are read, and the following four grids are basically the same. You can see that the writing is basically about 45MB, and if you read, 200MB or so
Pictured above is the CZ80. The basic writing is at 100MB, reading about 230MB, and 80 is really faster than 48.
Pictured above is Kingston DT100, write 16MB, I'm sorry, this is USB3.0 Mody, it is not enough patience to finish the file, cancel, read OK 150MB, behind the 200MB feel like repeating the file
Kingston DTSE9 G2 on the map, write data 21MB, gradually reduced to less than 20MB, but also very slow, Yan value really nothing useful. Too lazy to wait for it to finish canceling, there is no large file in the new disk, no test reading, it is estimated that almost
On the map Kingston DTmirco 64GB, write data more than 20MB, read data 130MB, USB3.1, because it did not play in the 3.0 port? Anyway, feeling is also general
On the map SanDisk OTG, write and read and Jinjia's DT100 has a trick, really slow 10MB and 100MB or so, fortunately there is an Android, or who want you
This U disk is embarrassing. . . I couldn’t find the Lord, and I didn’t move the data, so I couldn’t expect to meet his master someday. Intruder 2.0 product, not where to go soon
The figure above is the cool bean generation, USB2.0, the basic is a new disk, no data, only measured write. The speed is not bad
The picture above is the second generation of cool beans, USB3.0, write and read 46MB-100MB, the speed is also good
Pictured above is the second generation of Toshiba, USB3.0, write 170MB, read 220MB +, worthy of the price at the time of purchase, after two years is still fast
In the end, the old folk patriot butterfly pressed the array, USB1.0, and within 1MB, it was very fast in 2004. According to the price, it seems that nearly 400 softcoins are more expensive than all U-disks above. Purchasing power is higher than it is now, and doing electronic products is like stealing money.
------------------------------- The above U disk test finished, start measuring mobile hard disk
Mobile hard disk is obviously a series faster than U disk, and the gap between the protagonist and the runner in the movie is not too much to describe.
The figure above is a Seagate integrated hard drive, 2TB, USB3.0 interface, write stable at 539MB or so, read 139MB, I do not know why so slow, understand the explanation? The original mobile hard disk is almost the same, to test this one is good
Dangdang Dangdang, the main content to be tested in this article is the speed of writing and reading the Transcend MST400M.2-SSD. Writes are stable at more than 550MB and read at 340MB or more. If you are slow, it's hard to grab pictures
On the map of SanDisk, X300 series -512GB, 2280 of the article, a bit long, take the pin first to deal with, Xiao Lan light very pretty, haha. Speed ​​is also 520MB-330MB of leverage
----------------------------------- After testing M.2, the test SSD plus hard disk box
The figure above is Kingston V300, write about 500MB, read it 240MB, but there will be a Caton at the end of the write, should it be an index?
The picture above is Samsung 850PRo, write 550MB, read 352MB, faster, after all, a lot more expensive
The picture above is intel-730, write 550MB, read 330MB, and 850pro comparable, of course, the price is similar
In the final explosion, the garbage box was stuffed. The hard disk was stuffed in and couldn't come out. . Real garbage. The design is absolutely flawed.
Finally, a few words to summarize it
The original shape of SanDisk did not favor, has been abandoned, after the test is ready to use
Kingston is getting more and more garbage, but he will not buy it later.
Toshiba that is Japanese goods is not evaluated, read the picture and feel it
----------
To think fast, still have to use the hard disk, hard and fast M.2 is the best, is more than a U disk with a cable, if the file is small, U disk is fully qualified
SSD's mobile hard disk is also a good choice, it is estimated that after a while, large-capacity SSD prices dropped to civilian prices, and should be able to have hard disk manufacturers out of the original mobile hard disk.
A hard disk drive with a hard disk drive will slow down when it is written in the last few seconds, and it will also pause for a short while, similar to Thunder downloading a movie. M.2 and better multi-point SSD will not
Just stroll around the bosom's bobs and take a look. Thank you for joining us.
