Mac Pro RAID Card MB845Z/A 2009/2010/2012

In Stock

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 (NB. battery needs replacement, but is only necessary in case of AC power failure.) 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.

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 LevelDrive RequirementsBenefit
Enhanced JBODOne to four drivesA non-RAID configuration with the ability to migrate to a RAID set at any time
RAID 0 (striping)Two to four hard drivesMaximum performance and capacity for the most demanding I/O requirements
RAID 1 (mirroring)Two hard drivesMaximum protection for critical data
RAID 5Three or four hard drivesData protection, high performance,, and efficient capacity utilization
RAID 0+1Four hard drivesA mirror of striped drive pairs providing performance and data protection

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 volumes to meet your exact requirements.

Requires Mac Pro (early 2009), Mac Pro (mid 2010) or Mac Pro (mid 2012) and Mac OS X v10.5.6 or later.

Please note: The Mac Pro RAID Card occupies the top PCI Express expansion slot (slot 4) and you must have either all SATA or all SAS drives installed.
