Formatted using Windows XP SP3 to delete files written to it. After that, in Total Commander, I recorded 1605 files of various sizes (from 0 to 230 MB) with a total volume of 3 GB on it. The recording took 12.5 minutes, that is, the recording speed on a formatted USB flash drive is exactly 4 Mb / s. Their reading (copying to the hard drive) took 3 minutes 37 seconds, that is, the average reading speed was 14 Mb / s. There is no antivirus or other brakes. The flash drive is plugged into the noname controller PCI USB 2.0 (4+1)port VIA6212
