The package includes a PCI SATA card that also have an external SATA port, SATA cable, USB 2.0 cable, and power cable.
It must be cheaper to implement SATA than IEEE 1394 since SATA is standard on almost all desktop PC mainboards manufacturerd these days.
The case is only for PATA 3.5-inch form factor drives. It has 8MB buffer memory. I don’t know what that is good for. Maybe the price includes an 80GB 8MB buffer HDD. Confused.
