Installing Internal Storage Devices
Your Mac Pro has room for six internal drives: two optical drives and four hard disk drives. In most configurations, a single hard disk drive occupies the first hard drive bay and an optical drive is located in the top optical drive bay.
You can add up to three additional Serial ATA (SATA) 3 Gbit/s hard disk drives to the empty hard drive bays. The drives must meet these specifications:
åType: SATA 3 Gbit/s
åWidth: 3.9 inches (102 mm)
åDepth: 5.7 inches (147 mm)
åHeight: 1.0 inch
