Hi,

Thought I'd share this one with you, it's from Linus:

----

[...] get Jens' FIO code. It does things right, including writing actual pseudo-random contents, which shows if the disk does some "de-duplication" (aka "optimize for benchmarks):

http://freecode.com/projects/fio

Anything else is suspect - forget about bonnie or other traditional tools.

Thanks for your great work on fio, Jens!

It started as a way to help myself, so I'm just happy that it's helping others too :-)
