Product Information


OWC Aura Pro X2 Gen4 NVMe SSD Upgrade Solution

Tight deadlines, long nights, and terabytes of media – your Mac has been with you through it all. If storage is tight, there’s no reason to ditch the Mac you know and love. The Aura Pro X2 SSD gives you up to 16 x more space and the speed to keep up with your imagination today and tomorrow. Upgrade your Mac with Aura Pro X2 Gen4 NVMe SSD for a fraction of the cost of a new model and keep your Mac running for years.

Blazing Fast and Super Cool

Aura Pro X2 Gen4 NVMe SSD combines speed, stamina, and efficiency that will change the way you experience your Mac. With read speeds reaching 3168MB/s and write speeds of 3196MB/s, the 2TB Aura Pro X2 Gen4 NVMe SSD is up to twice as fast as the original SSDs, delivering performance on par with the latest models. It runs cooler and consumes less power than earlier SSD models, so you can run at peak for longer than ever.

Maintain Your Edge

When it’s go time, getting off the line and maintaining a high level of performance are equally important. Aura Pro X2 Gen4 NVMe SSD is engineered with advanced SLC caching, providing instant full-speed write acceleration, meaning those media projects and games stream fluidly and respond without lag time. You might even forget what that beachball looks like.

Continuous Compatibility

Aura Pro X2 Gen4 NVMe SSD is designed for the latest macOS versions (macOS High Sierra 10.13 and later), taking full advantage of the advanced features of APFS including: strong encryption, copy-on-write metadata, space sharing, cloning for files and directories, snapshots, fast directory sizing, atomic safe-save primitives, and improved file system fundamentals.

7% Over-Provisioning

OWC SSDs perform maintenance tasks in the background that optimise the health, performance, and endurance of your drive. These tasks utilise available unwritten space on the SSD. Aura Pro X2 SSDs reserve 7% of the overall drive capacity as free space to perform these normal maintenance tasks — making your drive a stable, dependable, and safe place to store all of your data.
