There has been a lot of discussion about TLER in the past, and I'm less convinced that it's a requirement for zfs than I used to think. I've been using WD Green (EADS) drives for two years without issue. They are ones that sleep and TLER settings could be changed on though. Many of the new WD Green drives (including some of the RE) use 4k sectors, which will wreak havoc on zpool performance. Other manufacturers are starting to use 4k sectors on their 5400 rpm drives as well so shop carefully if you decide to go with a lower spindle speed. I have not seen a 7200 rpm drive with 4k sectors, but I'm sure they exist. -B -- Brandon High : bh...@freaks.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
