Hardware is better for raid5 where some computation is required. For raid1 it is just a matter of having drives that can execute commands concurrently. That is, using 2 drives on the same IDE controller would be a bad idea, but SCSI is OK and SATA only permits one drive per controller anyway. There is not a lot of CPU overhead in mirroring. -- Les Mikesell lesmikesell at gmail.com
