Meet the Fastest OWC SSD Ever Built
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 four OWC Aura Ultra III NVMe M.2 SSDs under a finned heat sink cover that provides silent, throttle-free cooling. These "blade" style SSDs utilize Quad-Level Cell (QLC) 3D NAND with SLC caching and a Phison E12 controller with 7% over-provisioning.
All those "ingredients" combine to deliver over 6,000MB/s real-world speed with the highest reliability possible to satisfy the biggest storage performance appetite.
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 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.
Change Your Reality
Accelsior 4M2 offers performance gains in so many diverse ways that it will change your storage reality:
