On a sunny afternoon, I was doing laundry
Then it was a good time to pour the water in the basin into the pool
Suddenly, a small black object flashed
At the time, the only idea in my head: Grace? How do you think of a u disk?
Ah, u disk! ! ! I u disk too! I u disk too! I u disk too!
Fell off
No way, old ones don't come new
Still remember to see a post before
Look at the data, reason, look like SanDisk CZ73 good
Although the starting channel is Ma Yunjia, but in line with the concept of reliability, I still posted a second-hand East connection.
Although Ma Yun Jia, but this express delivery speed is not slow. 32G capacity, huge speed of up to 150MB/s (that is not telling you whether to write or read, really deep advertising ah)
The back is very common, is a lot of text
Paste a picture of the product line of the flash di U disk. Everyone looked at it. I bought it anyway.
U disk appearance can also be, the front is metal, the middle laser printed a SanDisk logo, feels pretty fine, just do not know how the life of the plastic parts behind
On the back of a large area of ​​plastic, look like can not help but fell, the latter shows the capacity of 32GB, and then the bottom is MADE IN CHINA
At the top, there is also an extension of the metal piece
U disk usb3.0 interface, work is very careful, the bottom of the interface is also used to bend the metal block inside the chip, to prevent friction inside the contents out
............................................. The appearance stops here, the following starts the test content.................. This is the line........................
The two software used did not detect what the master chip was, nor did it detect whether the memory chip was mlc or tlc. This should be true.
U disk is very hot, no load current 0.1A,
Write current 0.131A
Reading current 0.138A
There is a little current after it pops up
The first test software used is AS SSD. The test file size is 1GB. The data is very beautiful. It reads 142MB/s and writes it to 82MB/s. In addition, this U disk is very hot when working. After several tests, there will be performance loss. ......
Then there is the test software crystaldiskmark. The test file size is 1GB and the number of tests is 3, so this data will decrease slightly because
Random read under HDtune test
The actual file test read speed is very stable, the same as the test software data
Actual file write test, same as test software result
but! but! but! When the file transfer size exceeds about 1G, the write speed suddenly drops to 20MB/s
Immediately change to the AS SSD test software and change the test file to 3GB. The results are clear.
to sum up:
1, u disk as a whole read and write data is good, the reading speed is almost reached 150MB/s publicity on the packaging
2. The writing speed is about 90MB/s when writing files smaller than 1GB. If the writing speed exceeds this value, the writing speed will drop to 26MB/s. However, it is still a very good data, but we don't see usb3.0. u disk a large 10MB/s write speed
3, the overall is still more recommended to buy, Flash Di big brand, warranty, quality and the like are guaranteed, of course, if you buy anything Mackerel what silver can also be ah (manual slant smile)
thank you all!
