56 Chapter 3 Working Inside Your Computer
Installing Internal Storage Devices
Your Macintosh has three internal drive bays: one optical drive bay and two hard drive
bays. In most configurations, a single hard disk drive occupies the top hard drive bay
and an optical drive is located in the front optical drive bay.
You can add a Serial ATA disk drive to the empty slot in the hard disk drive bay. The
drives must meet these specifications:
 Type: Serial ATA
 Width: 3.9 inches (102 mm)
 Depth: 5.7 inches (147 mm)
 Height: 1.0 inch
Important: Use the original Apple cables that came with your Macintosh when you
install ATA or optical drives.
For more information about requirements and devices supported, see your
Apple Authorized Reseller and the support section of the Apple website at
