OWC Accelsior 4M2 16TB PCIe Card M.2 NVMe SSD

OWC Accelsior 4M2 16TB (4x4TB) PCIe M.2 NVMe SSD Storage Solution

Meet The Fastest SSD Available
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 Aura P12 M.2 NVMe SSDs under a finned heat sink cover that provides silent, throttle-free cooling. These “blade” style SSDs utilize Triple-Level Cell (TLC) 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 (Late 2019 - Mid 2023), 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).
