Product Overview
When OWC introduced its first Solid State Drive in 2010, it was built with a winning formula: high performance, reliability, and affordability—what we call "The OWC Difference." Today, that commitment continues with the Accelsior 4M2, pushing SSD technology to new heights. Perfect for demanding tasks like large format video editing, VR/AR/MR environments, and extreme gaming, the Accelsior 4M2 features four OWC Aura Ultra III NVMe M.2 SSDs under a finned heatsink for silent, throttle-free cooling. This powerhouse delivers over 6,000MB/s real-world speed with unmatched reliability.
