Get Back in the Game
After years of good, hard work, storage on your Mac is getting tight and load times and data transfers lag. You've invested years of gear, programs and customizations and it's not the time to switch. Upgrade with OWC Aura® N to make your Mac fast and more spacious than ever — for a fraction of the cost of a new model — and keep everything else just the way you like it.
Stretch Out and Run
Aura N2 expands your Mac with up to 1TB of storage space, so you can add to your media, games, and apps without picking favorites. It's advanced NVMe technology revives read speeds up to 1600MB/s write speeds up to 1100MB/s, giving your Mac the power to run like new again.
Sprints and Marathons
Aura N2 combines speed and stamina to prepare your Mac for the short race and the long haul. Engineered with advanced SLC caching, this SSD provides incredible burst performance for a faster and more responsive experience. Plus, the extra storage and speed can increase the working life of your Mac by years.
Right-Sized for Work and Play
The smaller stock SSDs for Mac can fill up quickly, especially with photo and video files, games, or even your email. Aura N2 SSDs are available in capacities up to 1TB, giving you more space to work and play. Newly calibrated to use less power and run cooler, Aura N2 is the best way to upgrade your PCIe equipped Mac.
No Hassles or Hacks Compatibility
Aura N2 SSD upgrades are precisely engineered for your Mac laptop, so you'll never need to compromise your data by relying on complicated software hacks or TRIM-enablers to get the most from your upgrade. Just install, migrate your data, and enjoy the great performance of flash storage with up to 8 times the capacity of the original drive.
High-Performance + High-Style
Your upgrade should be a seamless experience. That's why Aura N2 SSD upgrade kits come with Envoy Pro, the beautifully designed, high-performance SSD enclosure to reimagine your original drive.
When you remove your original SSD, it fits perfectly into Envoy Pro so you can transfer all your data to the new Aura N2 inside your laptop. Once the file transfer is complete, enjoy using your Mac's original SSD as a fast, external USB drive with transfer speeds up to 426MB/s.
7% Over Provisioning
OWC SSDs perform maintenance tasks in the background that optimize the health, performance, and endurance of your drive. These jobs take advantage of available, unwritten areas on the SSD. Aura N2 storage reserves 7% of the overall capacity as free space. Always. With this allocated free space, Aura N2 SSDs can perform these normal maintenance tasks making your drive more stable, dependable, and ultimately a safer place to store your data.
Quality That Lasts
Aura N2 SSDs are proudly designed in Austin and are backed by a lifetime of free, award-winning support.
The OWC Envoy Pro enclosure is specifically designed for use ONLY with the factory SSD installed in select Apple Macintosh computers. Do NOT attempt to install or use OWC Aura N, Aura Pro X2, Aura Pro X, or Aura SSDs in the Envoy Pro as you may damage the OWC drive, the enclosure, or both, and such damage is not covered under warranty.
The OWC Envoy Pro enclosure is not currently compatible with Apple PCIe NVMe drives.
