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:
Â Type: SATA 3 Gbit/s
Â Width: 3.9 inches (102 mm)
Â Depth: 5.7 inches (147 mm)
Â Height: 1.0 inch
For more information about requirements and devices supported, visit an Apple
Authorized Reseller or the Apple Support website at www.apple.com/support.
Use the original Apple cables that came with your Mac Pro when you install
or replace the optical drives.
Installing SATA 3 Gbit/s Hard Disk Drives
Your Mac Pro can accommodate up to four internal 1-inch-high SATA 3 Gbit/s hard disk
drives in the hard drive bays. If your Mac Pro comes with a single drive installed, it's in
the first bay. You can install drives in the second, third, and fourth hard drive bays.
