OWC

0GB Accelsior 4M2
PCIe M.2 NVMe SSD Adapter Card

High-Performance PCIe M.2 NVMe SSD Adapter Card

Build The Fastest SSD Available

When OWC launched its first Solid State Drive in 2010, it was engineered to deliver the same attribute formula that Mac and PC users expected from OWC external storage solutions:

High performance + high reliability + affordable price = The OWC Difference

Nearly a decade later, our commitment to that winning formula remains steadfast as we push the boundaries of leading-edge SSD development with the Accelsior 4M2. It’s ideal for uncompromised, data intensive, high bandwidth needs like large format video editing, VR/AR/MR environments, high transactional and complex calculation applications, and extreme gaming.

Accelsior 4M2 houses up to four M.2 NVMe SSDs under a finned heat sink cover that provides silent, throttle-free cooling. When tested with Aura P12 M.2 NVMe SSDs, Accelsior 4M2 delivers over 6,000MB/s real-world speed with the highest reliability possible.

Highly Versatile with Mobile Possibilities

Whether you have the Mac Pro 2019, a Mac Pro 2012 or 2010, or PC tower, Accelsior 4M2 can go to work for you. As a half-length x8/x16 compatible card, this game-changer offers the versatility you need, so you’re not tied to one PCIe slot size or limited by a space-confined computer case.

You can also enjoy the performance boosting benefits of Accelsior 4M2 with your Thunderbolt 3-equipped notebook computer, iMac workstation, or slot filled gaming rig. It’s Plug and Play easy with a PCIe expansion chassis like the OWC Mercury Helios 3S (sold separately and coming soon).

Change Your Reality

Accelsior 4M2 offers performance gains in so many diverse ways that it will change the reality of how you use a storage solution:

Stream and edit high-res video and graphics files without a glitch.
Experience faster previews, renders, and processing in VFX programs.
Keep page scenery and textures looking sharp and flowing uninterrupted in virtual reality environments.
Ensure augmented reality visualizations look life-like.
Change game levels seamlessly and play flight/driving/MMO games with continuously changing scenery and heavily personal preference modded games without micro-stuttering.
Give your computer a significant speed boost with improved system “snappiness”, a fast OS boot drive, or a bottleneck-free scratch drive.

Includes SoftRAID: Easy and Complete Drive Management

Accelsior 4M2 includes SoftRAID software to help you manage your data like a pro. You can maximize drive space, get the fastest access speeds, and protect against drive failure with plug-and-play simplicity. SoftRAID’s easy setup makes it a breeze to create RAID volumes by helping you through the entire process. Just decide what you’re using your RAID volume for and how much space to allocate to it. It's that simple to create your preference of speed and/or redundancy attributes of your data volume. Learn more about SoftRAID.

Professional Grade = Ready to Work

We understand having confidence in gear reliability is paramount to creative professionals. That’s why every Accelsior 4M2 pre-configured solution undergoes a multi-step performance certification prior to shipping. This ensures your Accelsior 4M2 arrives operating properly and immediately ready for demanding use.

2010-2012 Mac Pro Installs

Additionally, certain PCIe install configurations are not recommended or supported. Specifically, when certain double-width GPUs are installed in the bottom x16 slot (default / recommended), and the Accelsior 4M2 is installed in the neighboring x16 slot, either the GPU's shroud or its fans can contact one or more screws (or PCBA components) on the bottom of the Accelsior 4M2, causing potential problems. For this reason the XFX RX 580 cards sold by OWC — such as OWCMP1012R580V — cannot be used in conjunction with the Accelsior 4M2 in the above-noted configuration; the Accelsior 4M2 would have to be installed in one of the x4 slots higher up the logic board, which would result in reduced SSD performance.

The following commonly used double-wide GPUs have also been sold by OWC in the past, have been tested with the Accelsior 4M2 in the above dual x16 configuration, and did not make contact with the fans or other critical card components. If each card is installed properly according to Apple's PCIe card recommendations for these Mac Pro models, these configurations should work.
