For those not impressed with the stock options of Apple's MacBook Air SSD upgrades, look no further than this news post. OWC have just announced an SSD drive upgrade to 11.1-inch and 13.3-inch models in four sizes, 180GB, 240GB, 360GB and finally, 480GB. The drives use SandForce controllers and are up to 3.5 times faster in 4K random read/writes than Apple's factory options.
With the release of the 480GB model, this continues OWC's position as the only aftermarket SSD manufacturer for the 2010-based Apple MacBook Air. The OWC Mercury Aura Pro Express has a peak data rate of 275MB/sec which is a 68-percent increase over the factory-installed SSD's. Another benefit of the OWC drives is they don't slow down with use like ordinary SSDs. Over time traditional SSDs experience significant write speed degradation over repeated usage. The OWC Mercury Aura Pro Express SSD's ultra-efficient Block Management and Wear Levelling technologies are able to eliminate virtually any reduction in data transfer speeds over heavy long term usage of the drive and without dependency on less than effective OS TRIM management.
Very impressive OWC! Check out a bunch of information on the new SSDs at the Source.
