Why is that? Does the motherboard effectively just not have enough inputs for all the disks, so that's why you need dedicated hardware that handles some kind of raid configuration, and in the end the motherboard just sees it all as one drive? I never really understood what SCSI was for. How do the drives connect, SATA/PATA/something else?
SCSI is its own thing, to fix some issues with IDE iirc. The drive backplane is directly attached to the motherboard, well, more specifically to the RAID Card on the Motherboard, then the RAID card give the OS/Motherboard access to the configured RAID disk that you have created, but not to the disks themselves.
