That's only partially true. It appears as a single disk, but you need
special drivers for the hardware raid card.
With Software raid, it appears as a single disk ( /dev/md0 ) and
any combination of ide/scsi drives can be built into the array.

That's only partially true. It appears as a single disk, but you need

With Software raid, it appears as a single disk ( /dev/md0 ) and
any combination of ide/scsi drives can be built into the array.
