Directly mount any standard 2.5" drive with speeds up to 550MB/s. SSD is not included. No drivers required.

Give Your Mac Pro Tower or PC a SATA 6G Performance Boost
OWC Accelsior S is the simple solution to add a high speed SATA 6G drive to PCs or silver Mac Pro towers otherwise restricted to SATA 3G architecture. Combined with a high-performance SSD, Accelsior S brings cutting edge SATA 6G performance to your SATA 3G system.

Internal Storage Expansion at Lightning Speed
With more than 500MB/s of throughput, the OWC Accelsior S dual-lane PCIe 2.0 card delivers flexible storage expansion – with a speed boost – to your Mac or PC. Accelsior S is the perfect complement to OWC's Mercury Extreme Pro 6G and Mercury Electra 6G families of high-performance SSDs, allowing up to an extra 4TB of fast storage expansion.

Just Plug and Play
Mount a 2.5-inch drive to the Accelsior S, install in any available PCIe x4 (or greater) slot, and you're up and running with expanded high-speed storage. Use as a native, high-speed, boot drive or scratch-disk and boost capacity and performance. With no drivers or extra software needed, upgrading your PC or legacy Mac Pro tower with Accelsior S is a breeze.
