OWC Mercury AccelsiorM PCIe Controller Card Offers Plug and Play mSATA SSD Performance Boost to Mac Pros and PCs

Other World Computing today introduced the OWC Mercury AccelsiorM, a Mac and PC-bootable, fully supported PCIe controller card that accepts any standard 50mm mSATA Solid State Drive. By utilizing the fastest data interface available in a Mac Pro or PC—the PCIe slot—the Mercury AccelsiorM can offer data transfer speeds that exceed 3Gb/s SSDs….up to 380MB/s.

User-Friendly, Yet Robust for Demanding Uses

As easy to install as a memory module, yet robust enough to handle the rigors of professional multimedia production environments, the half-height AccelsiorM card is the clear choice for Mac Pro and PC owners who desire the maximum performance from their 3G data bus-based machines. Waiting for I/O-intensive apps like Photoshop, Final Cut Pro, or Avid Pro Tools to render, capture or process will become a distant memory; business critical applications are given an instant boost; and game level loading, object streaming, and save times can be reduced for more play time and less waiting.

Fully Bootable, No Drivers Needed

The OWC Mercury AccelsiorM PCIe controller card is AHCI compliant, so no drivers are required for a truly Plug and Play performance-boosting solution. Besides having the ability to turn a computer into a speed demon, this high-performance PCIe controller card is the only Mac-bootable, Mac supported card available.

Future-Ready for Growing Storage Needs

Greatly improving data transfer rates is only one of the benefits of the AccelsiorM. With the ability to use any standard 50mm mSATA SSD, consumers can meet expanding storage needs while extending the useful life of their investment in the AccelsiorM and their mSATA SSDs.

Keeps Drive Bays Open

Because AccelsiorM can utilize any open PCIe slot in a Mac or PC, consumers can keep their existing traditional footprint drive array intact and even add to their storage capacity.

Pricing, Availability

The Mercury AccelsiorM PCIe controller card is priced at $49.95 MSRP, comes with a three-year warranty, and is available immediately from Other World Computing as well as through select retailers. This controller card only model joins the previously announced, ready-to-run Accelsior PCIe SSD which features two on-board SandForce Driven “blades” with up to 960GB total capacity and data transfer speeds up to 820MB/s.

“Expanding our Accelsior line is quite rewarding because these products greatly extend the useful life of a Mac Pro or PC,” said Larry O’Connor, Founder and CEO, Other World Computing. “Whether looking for a turnkey solution or a bare card to add sourced drives to, an Accelsior PCIe solution is the product professionals should choose when seeking the highest level of drive performance from their machine.”

  • As I understand it, this van be used a bootable volume on a MacPro 1,1 or 2,1?

  • I have a Mac Pro 4,1 with a OWC SSD 256 GB about a year old. 6G SSD works great as boot drive. but this card sounds like it will speed up performance in the PCI #2 6G slot several hundred percent?
    Will it work OK?

    The accelsior 6G is how much faster as a blade O raid in PCI slot 2 than this new SSD single drive?

    You are really intelligent to optimize this previously unused capacity in Mac Pro Towers and windows based PC’s.


    • Accelsior delivers accelerated speeds up to 820MB/s read and 763MB/s write while the native SATA Revision 2.0 bus of the Mac Pro is limited to 300MB/s max – so you’re roughly looking at doubling the speed by upgrading from a single SSD to the Accelsior card.

  • A bit slow but the price definitely looks right. One question:

    >”that accepts any standard 50mm mSATA Solid State Drive”
    Does that include the drive found in the rMBP? While SATA, I heard that Apple used a somewhat different connector. This would be a natural fit with the Auro Pro upgrade.

  • Do you sell the 50mm mSata drives that are required? Is that the standard size of your Mac Book Air Aura SSDs (for example)? I can’t find the dimensions of the SSD “sticks” you sell, so just wasn’t sure if they are in fact 50mm…


    • We do not currently have any mSATA drives available. No, it is not the same form factor as the MacBook Air nor the MacBook Pro with Retina display flash drives.

      • Damn…Seems like there still isn’t a good way to utilize one’s old SSD when upgrading to one of your Aura SSDs. I have a Mac Book Air 2011 and although I would love to buy one of your SSDs, using my old SSD as an external drive isn’t that exciting or enticing. I would love it if I could use my Apple SSD in(side) another computer, so it could be utilized as a boot drive (opposed to a really extremely super fast external storage solution).
