High-Performance PCIe M.2 NVMe SSD Solution

Work Faster: over 6,000MB/s real world speed in RAID 01
Supercharges Mac and PC: ideal for Mac Pro 2019, Mac Pro 2012 or 2010, and PC towers
Highly Versatile: installs into a full-height, half-length x8 or x16 PCIe 3.0 or 2.0 slot2
Slot-Powered: no extra power cables needed
Includes SoftRAID: robust software for creating, monitoring, and managing advanced RAID sets

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, Mac Pro 2012 and 2010, 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

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.

RAID Made Easy

Harness the full capability of your OWC drive array with the included SoftRAID XT, the most powerful, intuitive RAID management software on the market for macOS and Windows. SoftRAID’s RAID creation and management technology has been finely tuned to perfection with over 20 years of development to provide rock solid protection of your data and optimize drive performance.

Packed with Features

SoftRAID XT provides an unbeatable combination of speed, protection, and compatibility:
Advanced: Create RAID 0/1/4/5/1+0 (10) arrays1
Protected: SoftRAID Monitor constantly watches your disks and alerts you if problems are detected
Validated: Volume validation ensures sectors can be read and parity is correct
Certified: Checks disks before use to ensure they are safe for data storage
Vigilant: Error prediction helps protect against unexpected failure
Universal: Move SoftRAID arrays seamlessly between Mac and PC2 with built-in OWC MacDrive technology

Beyond Hardware RAID

SoftRAID provides a level of storage performance that you simply can’t get with hardware RAID. Software RAID gives you increased power and control over your RAID drives and disks that hardware RAID can’t deliver and doesn’t lock you into technology that you can’t upgrade or expand.
