120GB Aura 6G
Solid State Drive

for MacBook Air 2012 Edition
OWC's Aura SSD provides upgrades from the original factory options for MacBook Air 2012.
  • More OPTIONS choose from 120GB, 240GB or 480GB models.
The Aura 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.
Once again, OWC provides Mac users an upgrade path that delivers higher performance, functionality, and reliability! Whether you own or are considering a 2012 base model 11″ MacBook Air with a 64GB Solid State Drive or the top of the line 13″ model with a 512GB SSD.
More Options
Unlike the factory pre-configured models with no other SSD choices offered, the OWC Aura 6G gives you the freedom to choose from a variety of sizes to meet your storage needs. 
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.
