Enjoy the Fast Lane

When your upgrade goal is to make your machine as fast as possible with maximum reliability and cost effectiveness, the Accelsior 1M2 is the answer. It utilises an open PCIe slot in your Mac Pro or PC to deliver the thrilling speed advantage of a NVMe PCIe SSD. It’s Plug and Play ready to put you in the fast lane of pure uncompromised storage performance.

Powered by The Best So You Can Be Your Best

At the heart of Accelsior 1M2’s mind-blowing power is an OWC Aura SSD that’s been engineered with fail-safes to increase longevity and preserve best consistent performance, especially in write-intensive workflows. From running double checks on data and correcting errors to ensuring the uniform use of its flash media, the Aura-based Accelsior 1M2 is a stable, dependable, and ultimately safer place to store your data.

Keep Your Cool Silently

When deadlines and workload pressures start to mount, the Accelsior 1M2 helps you keep your cool. An industrial quality black aluminium alloy heat sink with deeply grooved fins silently keeps the Accelsior 1M2 performing at its best so you can remain chill focused.

The Performance Advantage of NVMe

Non-Volatile Memory Express (NVMe) is a communication standard specifically built to optimise the performance of modern flash technology. It enables the Accelsior 1M2 to deliver significantly faster SSD performance vs an SSD using the SATA interface, a communication protocol that was originally designed for hard disk drives.

Perfect Inside or Out

By supporting PCIe 4.0 and earlier motherboards and able to plug into x4/x8/x16 PCIe slots, the Accelsior 1M2 is a perfect performance drive upgrade for a wide variety of full-sized and small form factor computers.

If your Mac/PC doesn’t have an open or compatible PCIe slot but is Thunderbolt 3 compatible, the Accelsior 1M2 can be used externally in a PCIe Expansion chassis like the OWC Mercury Helios 3S. (sold separately).
