PhotoFast outs first SSD upgrade kit for MacBook Air

Japan's PhotoFast had the distinction of becoming the first company to offer a storage upgrade for the new MacBook Air. The GM2 SFV1 Air not only gives an SSD in the narrow card format needed for the Air but goes beyond what Apple itself is delivering. It gives the 11-inch model its first 256GB option and uses a SandForce SF1200 memory controller that should be about 30 percent faster than the original, at 250MB per second peak in read and write performance.
