Our Tips Editor Vic Laurie says "Over the years I have accumulated a pile of
USB flash drives. They range from a really old (but still used) 256 MB USB
2.0 drive to a new 64 GB USB 3.0 drive. USB 2.0 flash drives can vary quite a
bit in performance and I wanted to see how fast some of mine were so I tried
out the freeware called USB Flash Benchmark. This is a small portable
application that provides an easy way to test how fast a drive can read and
write files of various sizes. It is mainly intended for flash drives."
