Sure, the only remotely user-replaceable component on the 11.6-inch MacBook Air are those tiny Toshiba SSDs, but PhotoFast's got what might be one of the most elegant upgrade solutions we've ever seen. The Air USB 3 Adapter gives you not only a brand-spanking-new 256GB module with a Sandforce SF-1200 controller, but a speedy USB 3.0 flash drive too -- which smartly doubles as the mechanism by which you move your old files over, as you can just transfer everything through the USB port. Once you're done swapping modules, the company says you'll see a 30 percent speed boost over the original drive, with reported transfer rates of 250MB/s on both sequential reads and writes. Shame the Japanese company didn't specify any sort of estimated release date or price.
