The Mac Pro RAID Card offers improved storage performance and

data protection to your Mac Pro system — up to 553MB/s of

sequential read performance in RAID 0. Ideal for video and creative

professionals with demanding storage needs as well as for tower

server applications, this hardware RAID option supports RAID levels

0, 1, 5, 0+1, and Enhanced JBOD. It has 512MB of cache and an

integrated 72-hour battery for protecting the RAID cache. The card

occupies the top PCI Express slot (slot 4) and connects to the four

internal drive bays.

With the Mac Pro RAID Card installed, high-performance 15,000-

rpm SAS drives may be used. SAS drives are sold separately and

available with the Promise 450GB SAS Drive for Mac Pro.

The Mac Pro RAID Card supports the creation of multiple RAID sets

in a system and multiple volumes per RAID set. For optimal disk

utilization in a RAID set, all hard drives should be the same size.

Using Apple's RAID Utility software (included with Mac OS X v10.5),

you can migrate the drives into a RAID set without reinstalling Mac

OS X or reformatting the drives, and you can customize your RAID

To enable your Mac Pro for hardware RAID, install the Mac Pro

RAID Card and two or more hard drives in bays 1 through 4. Each

RAID level has minimum requirements for the number of hard

drives:

RAID Level < Drive Requirements < Benefit

Enhanced JBOD < One to four drives < A non-RAID

configuration with the ability to migrate to a RAID set at any time

RAID 0 (striping) < Two to four hard drives < Maximum

performance and capacity for the most demanding I/O

requirements

RAID 1 (mirroring) < Two hard drives < Maximum protection for

critical data

RAID 5 < Three or four hard drives < Data protection, high

performance, and efficient capacity utilization

RAID 0+1 <

>

Four hard drives < A mirror of striped drive pairs

providing performance and data protection

Requires Mac Pro (early 2009), Mac Pro (mid 2010) or Mac Pro (mid

2012) and Mac OS X v10.5.6 or later.
