What are good benchmarking programs for measuring usb stick performances ?

What are the best (free) tools to test the speed of my USB drives? Reading, writing, general characteristics, I'm sure there is quite something to it. Where do I start?

Edit: I mean for Windows.

IOMeter is the most useful storage performance testing program I've seen for windows systems. It's not "point-and-click" simple, but fairly easy to grasp and fairly flexible as well.

On Unix, you can use the command dd like so:

time dd if=/dev/zero of=/mnt/usbdrive/zerofile bs=1024 count=1024

This will write to a file of 1M zeros to the device then return a message telling you the write transfer rate. Switch the terms for if and of to get the read transfer rate. Use varying values for count as desired.

You should try HD Speed. It's pretty light. ALternatively, you could just copy a large file to and from your USB key and measure how long it takes. Windows Vista and 7 will even tell you how fast its going.
