Then why do Hitachi and Seagate drives work flawlessly for me? We have some slow Seagate drives (ST32000542AS) in two chassises, and those just work. Another server, using Hitachi HDS721010CLA332 drives also just works - one dead drive during burn-in, and that was all. Western drives on direct attach works, but with SAS expanders, we get I/O errors (as reported by zpool and iostat) on high load.
