Work Faster Than Ever
Accelsior 4M2 NVMe SSD is one of OWC’s fastest SSDs, with over 6,000MB/s speed for large format video editing, VR/AR/MR environments, extreme gaming, and other high bandwidth needs. Available in capacities up to 32TB, Accelsior 4M2 raises the performance bar for Mac Pro (2019 - Current), Mac Pro (2010 - 2012), and PC towers.
It offers silent cooling via a finned heat sink cover and installation versatility with a half-length x8/x16 design. If a Mac/PC doesn’t have an open or compatible PCIe slot but is Thunderbolt 3-equipped, Accelsior 4M2 can be used externally in the OWC Mercury Helios 3S.3

The Performance Advantage of NVMe
Non-Volatile Memory Express (NVMe) is a communication standard specifically built to optimize the performance of modern flash technology. It enables significantly faster SSD performance vs an SSD using the SATA interface, a communication protocol that was originally designed for hard disk drives. With NVMe SSDs powering its heartbeat, Accelsior 4M2 delivers extreme data rates that will change the way you work or play.
More Lanes = Faster Throughput
Accelsior 4M2 was designed with a PCIe switch to let your computer address each of the M.2 NVMe drives at full x4 PCIe speeds instead of hard-limiting each drive to x2 PCIe speeds. When running in JBOD, where all four drives are typically not accessed at the same time, each drive has the unlocked capability to run at full speed.
2 to the Second Power
When over 6,000MB/s real world speed and 32TB of capacity isn’t enough to satisfy your needs, you can RAID two Accelsior 4M2 cards together to experience out-of-this-world performance.
