USB memory stick test software

Hi there all ,

Does there exist a piece of (freeware ?) software that tests the memory and speed of an USB memory stick (Pendrive) sorta the same way like MemTest x86 does for your pc memory ?

Theirs Winbench99 which is free to download though it’s a bit big around 121MB for the graphical version.

X-Bit labs used it in their performance comparision of USB 1 + 2 flash drives.
