I'm excited about having the Accelsior for a Mac Pro "hot rodding" option as a boot volume and/or a scratch volume. Consider this: the price of the 240G and 480G Accelsiors is comparable to similar capacity 6Gb/s SSDs - and that doesn't include the cost of special mounting adapters or cables or host adapters for those 2.5" SSDs. And the only 6Gb/s host adapter that will boot OS X is the ATTO ExpressSAS R6xx series starting at $995.Īs with with other solid state storage devices, the price per gigabyte for the Accelsior is higher than HDDs, but there's always some pain to get the gain. You can come close to the speed of a single Accelsior by connecting a single 6Gb/s SSD to a fast 6Gb/s Host Adapter (like we did), but the cost will balloon and internal installation can be tricky. DigLloyd Lab measured a striped pair at transfer speeds as high as 1190MB/s. A pair of Accesiors can be striped with Apple's Disk Utility to go even faster. It could be accused of "cheating" since it's really two flash storage modules in a hardware RAID 0 configuration. The OWC Accelsior is faster than any single drive option on the Mac Pro.
