Bring unparalleled performance to your Mac Pro or PC tower with the OWC Accelsior 4M2 PCIe 3.0 M.2 NVMe SSD Enclosure. Designed for those who demand the highest speeds and storage capacities, this enclosure achieves blazing-fast data transfer rates exceeding 6,000MB/s and offers up to 8TB of storage for high-resolution footage, photos, and games.
Since OWC introduced its first Solid State Drive (SSD) in 2010, it has consistently delivered high performance, reliability, and affordability. The Accelsior 4M2 continues this legacy by pushing the boundaries of SSD technology. It's the perfect solution for data-intensive tasks such as large-format video editing, virtual reality, augmented reality, mixed reality environments, complex calculations, and extreme gaming.
Underneath its finned heat sink cover, which ensures silent and throttle-free cooling, the Accelsior 4M2 houses four Phison E12 M.2 NVMe SSDs. These "blade" style SSDs offer up to 32TB of storage capacity and utilize Triple-Level Cell (TLC) 3D NAND with SLC caching and 7% over-provisioning. This combination delivers over 6,000MB/s real-world read and write speeds, ensuring the highest reliability for your storage needs.
The Accelsior 4M2 leverages Non-Volatile Memory Express (NVMe), a communication standard designed to optimize modern flash technology performance. This results in significantly faster SSD performance compared to traditional SATA interfaces, transforming how you work or play.
Versatility is key with the Accelsior 4M2. Compatible with Mac Pro models from 2010, 2012, and 2019, as well as PC towers, this half-length x8/x16 compatible card offers flexibility in slot size and space-constrained environments. Enhance your Thunderbolt 3-equipped notebook, iMac workstation, or gaming rig with plug-and-play ease using a PCIe expansion chassis like the OWC Mercury Helios 3s (sold separately). Experience up to 2,500MB/s read/write performance on the go, and enjoy the full 6,000MB/s capabilities at your desk.
The Accelsior 4M2's PCIe switch allows your computer to address each M.2 NVMe drive at full x4 PCIe speeds, maximizing throughput. For those needing even more power, RAID two Accelsior 4M2 cards together for extraordinary performance.
