We build and sell PCs. We need reliable USB drives for system image backup. However, these flash drives are not trusted brand names like San Disk, PNY or Samsung. For reliability and security reasons, we used "Check Flash" software to test the drives. There is an error of 20. If you buy big brand discs, this is a problem, but for ordinary discs, it is acceptable. Bought 20 more to complete our project, found 2 faulty USB drives (last 2 pics).
