I'm really impressed with btest. I've been doing a lot of disk testing with iozone, and iometer lately... and they all have their problems. btest, on the other hand, seems very full-featured, thoughtfully designed, and well documented. I especially appreciate how it allows you to control the dedup and compression ratios, for testing modern storage devices. This is probably my new favorite tool for doing I/O benchmarking on Linux hosts.
