SSD disk OWC Aura N2 512 GB M.2 PCI Express 3.1 NVMe QLC 3D NAND

The OWC Aura N2 512 GB M.2 PCIe 3.1 NVMe SSD expands storage and improves responsiveness for compatible Macs and other PCIe-equipped systems without replacing the computer. Using QLC 3D NAND and advanced NVMe protocol, this drive delivers read speeds up to 2200 MB/s and write speeds up to 952 MB/s while providing 512 GB of usable capacity in a compact M.2 form factor.

Advantages

Aura N2 combines high-capacity storage with improved sequential and burst performance thanks to advanced SLC caching and optimized firmware. The drive reserves 7% over-provisioning to support background maintenance tasks that help sustain performance, endurance, and data stability. It is calibrated to use less power and run cooler than some stock drives and requires no software hacks or TRIM-enablers for reliable operation when installed in supported systems.

Suitable for

• Expanding storage for Mac laptops with PCIe-equipped M.2 slots
• Photo and video libraries that require large, fast storage
• Gaming and application installations to reduce load times
• System upgrades to extend the usable life of an older Mac or PC

How to use

Power down your computer and follow the manufacturer’s instructions to access the M.2 slot. Install the Aura N2 into the M.2 connector and secure it according to the device’s mounting method. After installation, boot the system and migrate data from the original drive using cloning or system migration tools of your choice. Ensure the system firmware and operating system support NVMe drives and that any required installation steps for your Mac model are followed.

Recommendations

For best long-term performance, leave the factory-reserved 7% over-provisioning intact, keep firmware up to date, and use a verified cloning method when migrating an operating system. Avoid filling the drive completely to maintain optimal write performance and endurance.
