My old Chinese OTG-stick ( http://ammo1.livejournal.com/478652.html) quietly died. Having decided to order a new one, I discovered that there are at Aliexpress stick as USB 2.0, and USB 3.0 quite a bit more expensive. For the sake of the experiment ordered USB 3.0. He took the smallest by volume - 8 GB, to me this is more than enough.
Brand - Wansenda (yeah, I do this for the first time heard). The back of the packaging there is even an inscription in Russian and Ukrainian.
Speed on the package is not specified, only "High speed" and "High performance".
Never seen - blister is opened to pull the stick to break the packaging is not necessary.
On the one hand stick blue connector USB 3.0, the other connector MicroUSB USB 2.0.
Red activity LED is located inside the casing stick for some reason, just under the swivel piece of iron.
I tested the speed of the USB drive. CrystalMark shown on large files recording speed 13.8 MB / s, reading nearly 43 MB / s.
Test USB Flash Benchmark of http://usbflashspeed.com showed a slightly lower rate: record - 12.27 MB / s, read - 40.79 MB / s.
But this is only a test. Much more important, working at what speed flash card "in real life". I measured the speed with which are copied to the USB flash drive and with her films and photographs.
Video 1 GB: Recording - 13.5 MB / s (79), reading - 42.6 MB / s (25).
The folder 100 with pictures files 150 MB: recording - 11.6 MB / s (13), reading - 37.6 MB / s (4).
To check the actual capacity and filled the flash drive files from video and then compared them with the originals - all right.
Upd.: Connect the USB flash drive into the port 2.0 and got amazing results:
The speed is almost the same, here's a USB 3.0 in Chinese. :)
I ordered the stick purple. There is also a more white chornyo, green, red, blue. My 8-gigabyte costs $ 4.95, 16 GB - $ 6.50, 32GB - $ 9.80. Likely to have 16- and 32-gigabyte version of the operating speed will be different from what I measured.
bought here.
