I used an SV disk to upgrade one of my Tivo units, but I've never thought them appropriate for general use. It is my understanding that this type of disk is optimized for streaming workloads (reading large video files) and is not as stringent about error correction (who cares if you lose a few bytes of one frame of 30-FPS video-- you'll never see it). Under a typical NAS workload (much more random, smaller I/Os) I would expect higher average latency and thus poorer performance than even a bog-standard desktop drive. Never seemed like a good idea to me, and to paraphrase Richard Elling, expecting any kind of respectable performance from spinning media is a sucker's game. ;) Eric _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
