RAID5 Mac Pro RAID Card

Following today's Apple Stores updates, a new option has been added for the Mac Pro: RAID5 Mac Pro RAID card. This card supports RAID0, 1, 5, 0+1 and JBOD.

The Mac Pro RAID card offers improved performance and data protection to your Mac Pro system — up to 304MB/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 256MB 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.
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. Your Mac Pro system ships with each hard drive individually configured in the Enhanced JBOD level with Mac OS X installed on the drive in bay 1. Using Apple's RAID Utility software, you can migrate the drives into a RAID set without reinstalling Mac OS X or reformatting the drives, or you can customize your RAID volumes to meet your exact requirements.

This nice option has a price: US$999 and in addition the Mac Pro RAID card occupies one of the available PCI Express expansion slots.
