I bought two pieces, so all of the following is not a consequence of the marriage of a particular instance, but a lack of either the model as such, or a separate batch of flash drives. Recording speed: USB 3.0 jumps from 0 to 30 MB / s, never rises higher. Moreover, it jumps constantly: the graph is a high-frequency sinusoid (0-20-30-20-0-pause for a few seconds-again in a circle). The duration of the recording of a movie (i. E. one large file) with a volume of 5.5 GB is about 10 minutes (OS Windows 10 64 Bit), a USB 3.0 port on the motherboard, a similar (though much more expensive) flash drive from another manufacturer on recording without problems gives out here 150-160 MB / s and keeps them stably throughout the entire file transfer. Design: in principle, the extended USB connector is held normally, but if, when installing a USB flash drive into the USB port, you slightly touch it or slightly warp the USB flash drive, the connector immediately flies off the lock and retracts into the case. Summary: in my opinion, this is the worst flash drive of the 100,500 varieties that I used (Chinese goods from a well-known express site do not count). I really do not recommend.
