Are those IDE/ATA or SCSI connectors?
If this board is going into a server, they are going to want to put SCSI connectors on the board. ATA is cheap, SCSI is way fast. (not to mention that ATA slows down if you add more than one drive to a chain.
The superdrive will be connected to an IDE socket, but the raid array will be scsi.
They could put an adaptec pci card in, but why eat a pci slot?
Go configure a Dell server and see what kind of drives they put into their servers if you don't believe me.
