OWC 240GB Aura Pro 6G Solid-State Drive Upgrade for 2012 MacBook Air

Aura Pro 6G SSD / Flash Internal Drive Upgrade for 2012 MacBook Air: OWC's Aura Pro SSD provides upgrades from the original factory options for MacBook Air 2012. The Aura Pro SSD line features: 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. 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.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.
