Specs
- Mac Pro (2009-2010) - Installing Accelsior S into any open x4 or x16 PCIe 2.0 slot will deliver full throughput.
- Mac Pro (2008) - These models have two (2) PCIe 2.0 x16 slots, which enable Acceslsior S to deliver full throughput. Installing Accelsior S in of the two (2) PCIe 1.0 x4 slots will result in Accelsior S being addressed as a first generation one-lane card and will limit performance to 190-200MB/s real world data rates.
- Mac Pro (2006 - 2007) - These models have a PCIe 1.0 slot which cannot be configured to address Accelsior S as anything but as a first generation one-lane card, even with the Expansion Utility in OS X. As a result, Accelsior S performance will be limited to 190-200MB/s real world data rates. For maximum performance, we recommend installing a 2.5-inch OWC Mercury Electra 6G SSD in an open Mac Pro drive bay.
- PC - Use with a PCIe 2.0 x4 slot or better is recommended. Use with a PCIe 1.0 x4 slot will result in reduced performance.
480GB OWC Mercury Extreme Pro 6G 2.5-inch 7mm SATA 6.0Gb/s Solid-State Drive
- Use of a 2.5-inch SSD in a 3.5-inch drive bay requires an adapter bracket such as the NewerTech AdaptaDrive.
- Use of any SSD in an external enclosure is dependent on the power available from the enclosure. OWC Mercury Electra 6G and Mercury Extreme Pro 6G SSDs are engineered for use in any OWC Enclosure that supports 2.5-inch SSDs.

This provides probably the fastest SSD reads/writes available on the cMP at a reasonable cost. NVMe would be faster - but at a significant cost increase (and a little more configuration headache).
