High Performance Internal Flash Storage Upgrade

Designed for Mac

Once again, OWC provides Mac users an upgrade path that delivers phenomenal performance, functionality, and reliability! Whether it's for the base 11" model only offering a 64GB SSD or the base 13" model offering just a 128GB SSD, installing an Aura Pro 6G SSD is the best enhancement for the 2012 MacBook Air. Just like other OWC upgrades, we include a free 'how-to' video to make this an easy and money-saving DIY upgrade.

OWC redesigned its 3rd generation of OWC Aura Pro 6G SSDs with premium 3D NAND Flash and the latest controller technology to operate cooler and consume less power, resulting in improved battery life for your MacBook Air.
