If disk speed is *crucial*, there is a lot of stuff *MUCH* faster than
consumer SATA drives. From 15K RPM U320 SCSI drives on SANs with several
GBs of memory cache or RAID controllers with a little less cache, to
solid-state storage that leaves anything else into the dust (and costs an
arm and a leg).
Anyway, for a simple RAID1, SATA is probably a more cost-effective choice
than SCSI by far. And you are better of with software RAID than a
non-top-notch RAID controller.
But a top-notch RAID controller + SAF-TE hotswap bay will perform just as
well, if not better, AND it will be operator-friendly. That can be *very*
valuable depending on your needs. These controllers are available for SATA
or SCSI solutions.
