RAID and SCSI are not mutually exclusive for disks. You can have SCSI or
SATA (or IDE) disks in RAID arrays.
You might be right that SCSI would be more reliable than SATA (opinion
seems to vary), but 2x SCSI disks in RAID1 would likely be more reliable
again. It would of course also be more costly. I always suppose that a
disk failure is inevitable and although I may have backups, I'd really
rather buy the extra disk rather than have to restore an entire system from
backups whenever the failure finally happens.
