Highlights
OWC's A Closer Look
And unlike the factory pre-configured models with no other SSD choices offered.
Now thanks to OWC and the Mercury Aura Pro Express SSD line, you can buy the MacBook Air you want today and enjoy the
flexibility of upgrading for higher performance when you need it.
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. With this technology, even MLC-based SSDs can operate for years in demanding use applications without daily write restrictions. This adds up to a MTTF that is higher than most enterprise class hard drives and SSDs on the market today.
Additionally, as there are no volatile memory elements in this storage device, the need for cache is completely negated. The drive is just that fast from the get-go!
High Performance Internal Storage
Replace your conventional hard drive with a reliable solid state drive. Unlike traditional hard disk drives, OWC solid-state drives have no moving parts, resulting in a quiet, cool, highly rugged storage solution that also offers faster system responsiveness.

BENCHMARKS

Write stress test consists of playing one 720P HD movie in Media Player Classic, one 480P SD movie playing in VLC, three movies downloading simultaneously through iTunes, and one 1080i HDTV stream being recorded through Windows Media Center over a 15 minute period. Higher IOps and MB/s rates with lower latency times are desired.Block Management & Wear Leveling offers highest endurance, performance and power efficiency in a SSD.

Read stress test consists of loading each of the following games: Steam, Grand Theft Auto 4, Left 4 Dead 2, and Mass Effect 2, as well as textures as the game progresses.

One of the leading benchmarking applications for comparing side by side drive performance.
