Original posting: The US Apple store isn't up yet but the UK one shows at least ONE Update today: UK STORE IMAGE UPDATE: US store was updated. The option is $999. Christ that's overpriced, I bought a RAID card for a mac pro for less than $200.. However, this is likely the only S.M.A.R.T. and bootable RAID card available for the mac pro, so you be the judge. UPDATE 2: From Apple.com (2) Testing by Apple in July 2007 using preproduction Mac Pro RAID Card and software, and shipping 3.0GHz 8-core Mac Pro units. Testing conducted using Iometer 2006.07.27 with a 30-sec ramp-up, 5-min run, 512KB request size, and 4 outstanding IOs. System configured with the OS and test volume on a single RAID volume. Performance tests are conducted using specific computer systems and reflect the approximate performance of Mac Pro RAID Card. (3) Supports Mac OS X only. It looks like it wont work in bootcamp! WATCH OUT! Update 3 It looks like it works with the internal hard drive bays, even though it's PCIe.
