About OWC / Other World Computing Accelsior 4M2

Become a part of the digital revolution with the Accelsior 4M2 2TB NVMe PCIe 3.0 M.2 Internal SSD, the fastest OWC SSD ever built. With an unprecedented speed of 6,000MB/s, this SSD leverages the power of M.2 NVMe technology to deliver breakthrough performance for large format video editing, VR/AR/MR environments, and extreme gaming.

Since the launch of our first Solid State Drive (SSD) in 2010, OWC has been committed to delivering high performance, high reliability, and affordable solutions. The Accelsior 4M2 is a testament to this commitment, pushing the boundaries of SSD development to satisfy the most data-intensive and high-bandwidth needs.

Underneath the finned heat sink cover of the Accelsior 4M2, which ensures silent, throttle-free cooling, lie four Phison E12 M.2 NVMe SSDs with a combined storage capacity of 2TB. These blade-style SSDs utilize Triple-Level Cell (TLC) 3D NAND with SLC caching and 7% over-provisioning, delivering over 6,000MB/s real-world read and write speeds with the highest possible reliability.

The Accelsior 4M2 is powered by Non-Volatile Memory Express (NVMe), a communication standard specifically designed to optimize the performance of modern flash technology. This enables significantly faster SSD performance compared to SSDs using the SATA interface, a protocol originally designed for hard disk drives.

The Accelsior 4M2 is highly versatile and compatible with a range of devices, including the Mac Pro 2019, Mac Pro 2012 or 2010, and PC towers. Its half-length x8/x16 compatible card offers the versatility you need, without being tied to one slot size or limited by a space-confined computer case.

With a PCIe switch designed to let your computer address each of the M.2 NVMe drives at full x4 PCIe speeds, the Accelsior 4M2 delivers faster throughput. When running in JBOD, each drive has the unlocked capability to run at full speed.

The Accelsior 4M2 is not just about speed and capacity. It offers performance gains that will transform how you use a storage solution. Whether you're streaming and editing high-res video and graphics files, working in VFX programs, gaming, or using VR/AR/MR environments, the Accelsior 4M2 ensures seamless, glitch-free performance.

The Accelsior 4M2 comes with SoftRAID, a user-friendly drive management system that makes it easy to create RAID volumes. This feature allows you to maximize disk space, get the fastest access speeds, and protect against disk failure with Plug and Play simplicity.

Every Accelsior 4M2 pre-configured solution undergoes a multi-step performance certification prior to shipping to ensure it arrives operating properly and ready for demanding use. Trust the Accelsior 4M2 2TB NVMe PCIe 3.0 M.2 Internal SSD to deliver the performance and reliability you need.
