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 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.

Multiple RAID Levels

Create advanced RAID 0/1/4/5/1+0 (10)1 volumes for higher performance and/or redundancy.²

Disk Health

More accurate than SMART, SoftRAID protects your data by alerting you to issues before anything happens, providing peace of mind and giving you more time to address issues. Solutions that rely exclusively on SMART data can be seeing performance loss or corruption before flagging an issue.

Cross-Platform

Built-in MacDrive technology lets you read/write SoftRAID HFS+ RAID 0/1/5 arrays and use them interchangeably between Windows and macOS.

Flexible, Upgradeable

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 between computers.

Compatible

Works with macOS 10.12 or later and Windows 10 and later.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.

• RAID 4/1+0 (10) is available for Mac only at this time.
• Improved data protection/redundancy requires RAID 1/4/5/1+0.
• 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 unique, valid license per computer. Additional licenses can be purchased anytime.
