OWC's Aura Pro SSD provides up to nearly 8x the capacity over factory SSDs while offering Faster Performance vs. Factory Options.

The Aura Pro SSD line features industry leading SandForce DuraClass Technologies:

  • DuraWrite extends the endurance of your Solid State Drive (SSD).
  • Intelligent Block Management & Wear Leveling automatically distributes data evenly across the entire SSD.
  • Intelligent Read Disturb Management spreads the active read/write across the flash components eliminating data corruption caused by constant use.
  • Intelligent "Recycling" for advanced free space management gradually re-writes data across the SSD over time to ensure data never gets corrupted.
  • RAISE (Redundant Array of Independent Silicon Elements) protects the data on your drive similar to having a RAID setup.
  • Best-in-Class ECC Protection for longest data retention and drive life.

The Envoy offers the perfect companion storage solution for your MacBook Air

Get the ultimate combination of elegance and functionality in a sleek, portable external storage solution designed to complement the MacBook Air - in both appearance and performance. Its super-speed USB 3.0 interface is capable of speeds up to 500MB/s to ensure your workflow moves as fast as you do, and is backwards compatible with USB 2.0. Its bus-powered design means no AC power adapter is required making it an ideal portable Plug and Play solution - just plug the USB cord into your computer and the Envoy is ready to go.

More Options

Once again, OWC provides Mac users an upgrade path that delivers higher performance, functionality, and reliability! With the 2012 base model 11" MacBook Air only offering a 64GB flash module and the base 13" model offering just a 128GB flash module, installing an Aura Pro 6G flash module can increase storage capacity up to 8X higher! Plus for the upgradeable models, unlike an upgrade from the factory at the time of purchase, this OWC bundle includes an Envoy to keep that factory flash module working for you as a super fast, external storage solution!

Better by Design

"Mean Time To Failure" - We all know that nothing lasts forever. But that doesn't mean you shouldn't get the most out of your investment. OWC SSD with DuraWrite Technology, optimizes writes to the flash memory over conventional controllers increasing the overall endurance and reliability of the complete SSD. Highly intelligent block management and wear leveling also extends the overall endurance. This adds up to a MTTF that is higher than most SSDs and enterprise class hard drives on the market today.

Synchronous Interface NAND

To achieve the higher bandwidth potential of the SATA 6Gb/s bus standard, the OWC Aura Pro 6G SSDs utilize Tier-1 Synchronous NAND instead of commonly utilized Asynchronous NAND. Synchronous NAND enables reads and writes to be "synced" with the SSD processor's clock signal for maximum data throughput.
