Installing internal drives
Your Macintosh can hold up to four internal storage devices, including a floppy disk drive, a CD-ROM drive, and two hard disk drives (several capacities are available). These drives may already be installed. If you want to add an internal drive to your Macintosh, see your Apple-authorized dealer.
