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) hard disk drives to the empty hard
drive bays or up to four Serial Attached SCSI (SAS) drives. The drives must meet these
specifications:
 Type: SAS or SATA 3 Gb/s
 Width: 3.9 inches (102 mm)
 Depth: 5.7 inches (147 mm)
 Height: 1.0 inch
Important: To install SAS drives in your Mac Pro, you must also install the optional
Mac Pro RAID Card.

Authorized Reseller, the Apple Store at www.apple.com/store, or the Mac Pro Support
site at www.apple.com/support/macpro.
Installing SAS or SATA 3 Gb/s Hard Disk Drives
Your Mac Pro can accommodate up to four internal 1-inch-high SATA or SAS 3 Gb/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.
