Big spenders in need of fast and reasonably-sufficient storage for their 2010 MacBook Air will be pleased to know that OWC (Other World Computing) has released such a solution, a 480GB SSD powered by SandForce's SF-1200 controller.
OWC's 480GB Mercury Aura Pro Express has a MTTF of 2 million hours, is capable of read and write speeds of up to 285 MB/s and 275 MB/s, respectively, and is backed by a three-year warranty. It all sounds good until you reach the pricing though - $1,579.99 .
