Inside the Mac Pro: Hard drives
The standard Mac Pro includes one 250GB hard drive. Like the Power Mac G5, the Mac Pro uses SATA hard drives. But while the Power Mac supported SATA drives with a maximum bandwidth of 1.5 gigabits per second (Gbps), the Mac Pro supports the second generation of SATA drivesâsometimes known as SATA II or SATA-300âwhich have a maximum potential bandwidth of 3 Gbps. However, this doesnâ actually translate into doubled speedâdrive mechanisms arenât currently fast enough to pump out that much data in that amount of time.
