Not all USB Drives are Created Equal

Most USB 2.0 flash drives look the same, but that doesn’t mean they perform the same. Differences in the type of memory and, to a lesser extent, the type of I/O controllers used by USB drives can make one device perform two or three times faster and last (theoretically, at least) 10 times longer than another, even if both sport the USB 2.0 logo. Unfortunately for the average user, there are no accepted industry standards or certifications to judge what’s inside a USB 2.0 flash drive on a store shelf. Without checking reviews or running benchmarks, the only rule of thumb is that the more expensive drives (and those which post performance numbers on the packaging) will tend to be the fastest and, perhaps, last the longest
