Product Overview
When OWC launched its first SSD in 2010, it was designed with a formula that Mac and PC users have come to trust: high performance, reliability, and affordability—"The OWC Difference." This commitment continues with the Accelsior 4M2, engineered for demanding, high-bandwidth tasks like large format video editing and extreme gaming. It houses four OWC Aura Ultra III NVMe M.2 SSDs under a finned heatsink, offering silent, throttle-free cooling. With advanced QLC 3D NAND and a Phison E12 controller, the Accelsior 4M2 delivers over 6,000MB/s real-world speed and unmatched reliability.
