OWC Mercury Accelsior PCIe SSD
Up to 960GB of storage* in a PCIe slot running at PCIe speeds (potentially faster than 6G SATA!).
That is, for Mac Pro users. One more reason to buy a Mac Pro.
This card is a problem-solver for Photoshop and Lightroom and video users looking for ~1TB of fast storage without using up any drive bays.
Exciting! I expect to have one of the first units for review very soon.
For 2009 and later Mac Pros with PCIe v2.0, the card is a 2-lane card supporting up to 1000MB/sec throughput. The 2008 and older Mac Pro models are 500MB/sec, though there might be a single slot in the 2008 model that does 1000MB/sec (not sure). Note that these speeds are bus speeds. The card is unlikely to perform at full bus speed.
* 1TB of flash memory (1024GB), but with 7% internal over-provisioning for reliability (good!), usable space as a volume on your desktop is 960GB.
