My mileage does vary! On a 4 year old 84 disk array (with 12 RAID 5s), I replace one drive every couple of weeks (on average). This array lives in a proper machine-room with good power and cooling. The array stays active, though. -Luke _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
