Failure ratio does not depend on interface. "Enterprise" grade SATA drives have the same build quality as with their SAS brothers and sisters. With RAIDz2 or -3, you're quite sure things will work fine even after a disk failure, and the performance penalty isn't that bad. Choosing SAS over SATA for a single setup must be more of a religious approach roy _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
