    Dear all,

    According to this webpage on Mid 2012 Mac Pro (" http://support.apple.com/kb/SP652 "), Storage
    Four 3.5-inch cable-free, direct-attach drive bays with built-in independent 3Gb/s Serial ATA channels; four internal drive carriers included

    Up to 8TB of internal storage7 in bays 1 through 4 using hard drives or solid-state drives in the following capacities:
    - 1TB or 2TB hard drives, Serial ATA 3Gb/s, 7200 rpm, 32MB cache
    - 512GB solid-state drive, Serial ATA 3Gb/s

    Does that mean we cannot exceed 8Tb of space altogether, and the disks must be in 1tb/2tb (spinning drives) and 512gb (ssd) max? Anyone tried putting a 4TB WD green/black/any color into Mac Pro? 8tb max by today's standards is really a limitation...

    I think that was just the maximum you could order from apple, but I am pretty sure you can fit 16 TB with a 4 TB drive in each bay. I'm really not sure though, can someone confirm this please?

    There is no technical limitation to 2TB. It's just what was available when the documentation was written.

    Mine isn't quite that maxxed out, but I do have a pair of 4TB Seagate drives in the drive-bay sleds and they initialized fine and are working flawlessly. If you count the additional 2TB of SSD storage, the systemwide storage is greater than 8TB. :p

    The individual drive bays seem to accept 4TB drives without a problem, even if Apple doesn't offer them oem.

    Posters are correct - that was simply the largest drives as tested by apple at the time of release.

    Many of us are running more than that in our setups; I have 13.25TB total in mine.
