The Mac Pro comes with four 3.5-inch drive bays for an enormous amount of internal storage — up to 8TB when you install four 2TB Serial ATA 3Gb/s drives.1 Each bay provides its own independent 3Gb/s channel for fast access to data. And thanks to the cable-free, direct-attach installation system, adding (or replacing) hard drives is a surprisingly simple process.
Choose solid-state for ultimate performance.
Mac Pro also gives you the option to add up to four 512GB solid-state drives — or any combination of solid-state and hard drives. Solid-state drives have no moving parts and are capable of accessing data at speeds up to 266MB per second, which is up to twice the speed of hard drives. The result? Incredible performance on a range of data-intensive tasks, including up to 2.5x faster video encoding using solid-state drives compared with hard drives.2
Double-layer burner times two.
Sure it’s great to have one 18x SuperDrive at your disposal, but think how much more productive you could be if you add a second optional SuperDrive. Imagine backing up your data to two double-layer DVDs at once. Or burning Aperture projects to one DVD, while importing music from a CD into your iTunes library. With two optical drive bays in every system, the Mac Pro lets you do exactly that.
SSD I/O Performance. Up to 2.5x faster than 7200-rpm hard disk drive.
Testing conducted by Apple in May 2012 using preproduction Mac Pro 12-core 3.06GHz units configured with 12GB of RAM, 1TB 7200-rpm hard disk drive and 512GB solid-state drive. Testing conducted using Iometer 2006.07.27 with a 30-second ramp-up, 5-minute run duration, 128KB request size, 8 outstanding IOs, and 150GB test file. Average rotational media performance calculated by creating the test file on the outer, middle, and inner sectors of the drive and averaging the results from all three measurements. Performance tests are conducted using specific computer systems and reflect the approximate performance of Mac Pro.
