Use a good card like the 3ware 7500 series (parallel IDE ATA) and there
are no problems using IDE ATA drives. 3ware uses hardware raid unlike
the garbage promise chips that Claim hardware raid, but are not in
reality.

IED Raidsets on 3ware show up as scsi drives to the system.

3ware is one of those rare companies that have Great linux support.

You get what you pay for. The controller card may cost as much or more
than the drives.

Linux SATA support is still a little weak, but the performance can be
much better for the higher-end SATA drives. Use of a good raid card like
3ware makes Linux compatability a non-issue.

I agree that software raid should be avoided.
