[Serious] Where can I get a USB Flash tester?

I have a couple of usb flash drives and I want to measure their read/write speeds.
Anyone know where I can find downloadable benchmark software?

Thanks

Sisoft Sandra does this if i'm not mistaken.

I think KDE on linux gives transfer rates. You could just drag and drop large files back and forth and see what rates you get.

It would take all of 5 minutes to write one. Maybe 10 if you wanted to do a spread-spectrum analysis with different file sizes.

Moved.
