In some cases, SAS outperforms SATA. I don't know what circumstances those are. I think the main reason anyone buys SAS disks is for reliability reasons. I maintain data centers for two companies, one of which uses all SAS, and the other uses mostly SATA. I have replaced many SATA disks in the last 3 years, and I have never replaced a single SAS disk. I don't know if my experience would be reflected in the published MTBF of the disks in question. Sometimes those numbers are sort of fudged, so I don't trust 'em or bother to look at them. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
