I took the option for 64GB and 32GB. The description states that both USB flash drives are version 3.0. At least, I did a selection in search of version 3.0. BUT! It turns out they are designed for Windows and above! I use the seven, so I'm just shocked by the low speed of copying or moving both during normal use on the desktop and in the office. Yes, I have old ten-year-old Qumo, SP, Transscend flash drives and it works several times faster! And they are all versions 2.0! On otg they generally fly! And here is a complete ahtung . I could not copy 32GB files to a 64GB flash drive. I set to be copied back at 7 pm. Copying went on all night and there was still a lot to complete . Speed 325kb / s, etc. Are you kidding me?! Yes, on otg the speed can be 1.6mb / s (maximum!), But my old flash drives fly at a speed of 4-6mb / s! What kind of mockery is this?! I made screenshots of tests before copying files. 1st screen - 32gb, 2nd - 64. It is a pity that the manufacturer removed the seven from support. I used the seven, and I will use it.
