Ordered from the Chinese. Immediately after receiving it, I did a couple of tests in well-known programs and then began to copy music to it. And here the well-known Sandisk sore happened - there was a failure and the write protection worked. That's it, the flash drive has become read-only and no reformatting and resetting utilities can fix this. Fortunately, the flash drive was original, sent it under warranty (Sandisk knows about this feature and change it without problems) and sent a new one, only I had to pay 300 for sending it. This new one, although it heats up quite a lot, works to this day. But USB 3.0 does not work in the extension cable from the PCI hub, although other USB3.0 and USB2.0 flash drives work in it. The speed is normal, there are not enough stars from the sky, but it also records movies in USB2.0 at a minimum speed of 15-18 MB / s.전체 리뷰보기
