The Fastest SSD We’ve Ever Built
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 8.0TB, 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 (sold separately and coming soon).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 8TB of capacity isn’t enough to satisfy your needs, you can RAID two Accelsior 4M2 cards together to experience out-of-this-world performance.
Includes SoftRAID: Easy and Complete Drive Management
Accelsior 4M2 includes SoftRAID software to help you manage your data like a pro. Use it to maximize drive space, get the fastest access speeds, and protect against drive failure with plug-and-play simplicity. SoftRAID’s easy setup makes it a breeze to create RAID volumes by helping you through the entire process. Just decide what you’re using your RAID volume for and how much space to allocate to it. It's that simple to create your preference of speed and/or redundancy attributes of your data volume.
- Up to 86% faster vs AppleRAID
- Create advanced RAID 0, 1, 4, 5, 1+0 (10) volumes for higher performance, greater data reliability, and/or redundancy
- Enterprise-class monitoring for disk and RAID volume health with email notifications
- Volume validation to ensure sectors can be read, parity is correct, and minimization of volume failure
- Disk certification checks that your disks are safe to store data on before use
- Disk failure prediction with early warning helps protect you from sudden disk failure
