Let me say up front that most of my (work) experience comes from SCSI. But
the principles hold for ATA drives as well.
One thing that is unique to ATA drives is the fact that you get only 2 disks
per channel - one master and one slave.

It is not possible to use the so-called hardware RAID controller as RAID in
