Don't go down this road. Do NOT use RAID 0. This will quadruple your
chances of a failed drive giving data loss.
Put the transaction log on a RAID 1 or even RAID 10 setup.
But the data on RAID5 if you want to minimize disks. Otherwise you can use
RAID 1 or 10 if yo can spare the disks.
Move the backup drives to a different machine. If this one fails (say bad
fan, it overheats destroying memory or CPU) those backups are of limited use
untli you can build another srever to put them in.
