- Quote of the day (fio mailing list, 12.04.2012): 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" (also known as "optimize for benchmarks): http://freecode.com/projects/fio Anything else is suspect - forget about bonnie or other traditional tools.
