Variable (7.5 Mb/s - 16.6 Mb/s) USB 2.0 write speeds The first 200 MB are written at 61 Mb/s to 64 Mb/s on a USB 3.0 drive, and subsequently the write speed varies between 16.6 Mb/s and 21 Mb/s, and even 32 Mb/s on rare occasions. I've been using a flash drive for a while now, and I haven't had any problems with it being jammed up. Take as many as you like, but no more than 500.
