34K*3 = 102K. 12K isn't anything to sneeze at :) So you'll need six disks to do what one SSD does: three spindles, and two (mirrored) disks on each spindle for redundancy (drives are riskier than SSDs). _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
