Apple forces PhotoFast to abandon 256GB upgrade kit for MacBook Airs
 

Remember that peppy aftermarket 256GB SSD upgrade from PhotoFast that easily smoked the SSD found in Apple's latest MacBook Air? It's gone upon Apple's request, just like those HyperMac batteries before it. The risk of losing access to Apple's product licensing program was just too grave a threat to ignore. So, enjoy your 160MBps max SSD transfer rate MBA owners, you'll get that 250MBps sequential read/write speed bump only when Apple's good and ready to provide it themselves
