Upgrade Your Tower with Extreme NVMe SSD Performance
Push your workstation beyond its factory limits with the OWC Accelsior 4M2, one of the fastest PCIe SSDs on the market. Designed for professionals and power users, this adapter card unleashes staggering real-world speeds of over 6,000MB/s, transforming your workflow. Whether you're editing large-format video, developing in VR/AR environments, or seeking a competitive edge in extreme gaming, the Accelsior 4M2 delivers the high-bandwidth performance you need to eliminate bottlenecks and work faster than ever before. With capacities available up to an incredible 32TB, you can consolidate massive projects and media libraries onto a single, lightning-fast card.
Engineered for maximum throughput, the Accelsior 4M2 utilizes an advanced PCIe switch that allows each of the four installed M.2 NVMe SSDs to communicate at their full potential. This intelligent design bypasses the performance-limiting compromises found in other cards, ensuring you get the speed you paid for. Installation is a breeze in any compatible Mac Pro (2019, 2012/2010) or PC tower with a PCIe slot. The card is slot-powered, requiring no messy extra power cables, and features a robust, fanless heat sink for completely silent and reliable cooling.
The Accelsior 4M2 is more than just hardware; it's a complete performance solution. Included is the full version of SoftRAID XT, the most powerful and intuitive RAID management software available for both macOS and Windows. Create and manage advanced RAID arrays (0, 1, 4, 5, 1+0) to customize your setup for maximum speed, data protection, or a combination of both. SoftRAID constantly monitors drive health and validates data to protect against failure, giving you professional-grade storage control and peace of mind. For ultimate versatility, if your computer lacks an available PCIe slot but has Thunderbolt 3, you can even house the Accelsior 4M2 in an external OWC enclosure to take its performance on the go.
