Accelsior 4M2 NVMe SSD is OWC’s fastest SSD ever 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 is the ultimate performance drive 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 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 offers the fastest data rates ever delivered by an OWC SSD.
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.
Easy and Complete Drive Management with SoftRAID XT
SoftRAID XT is 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. It is packed with features like multiple RAID options, validation and verification of drives, and predictive disk failure with SoftRAID Monitor. SoftRAID provides a level of performance that you simply can’t get with hardware RAID.
Multiple RAID Levels
Create advanced RAID 0/1/4/5/1+0 (10)1 volumes for higher performance and/or redundancy.2
SoftRAID protects your data by alerting you to issues before anything happens, ensuring you’re protected when you’re on a critical deadline.
Built-in MacDrive technology lets you read/write SoftRAID RAID 0/1 arrays and use them interchangeably between Windows and macOS.
With SoftRAID you’re not locked to expensive hardware. SoftRAID is upgradable and portable.
Easy License Management
New license management enables quick activation or deactivation so your license can move moved between computers.
Works with macOS 10.12 or later (including Big Sur), M1 Macs, and Windows 10.3
SoftRAID is ideal for anyone who needs to safely store and backup massive amounts of data, including video editors, audio producers, photographers and graphic designers.
SoftRAID Pro Tip: Need even more power and flexibility? Upgrade to SoftRAID Pro to spread volumes over two or more disk enclosures for incredible performance! (Impossible with hardware RAID.)
- RAID 4/5/1+0 (10) is available for Mac only at this time.
- Data protection requires RAID 1/4/5/1+0.
- SoftRAID XT and SoftRAID Pro work with macOS 10.12 or later and Windows 10. M1 Macs require macOS 11.3 and later. SoftRAID serial numbers work on both Mac and Windows. SoftRAID is licensed per computer. In order to use SoftRAID on multiple computers you will need a valid license, which can be purchased anytime.
