It was good while it lasted.

Per 9to5 Mac, Apple has quietly stopped third-party outfitter PhotoFast from selling the 256GB MacBook Air SSD upgrade kit, the company’s product page returning a 404 error this morning.

The kit included a 256GB upgrade chip as well as a USB 3.0 housing for the 64GB chip currently in the 11.6″ MacBook Air. Plus, it could read and write at 250MB/s while Apple’s SSD clocks in between 150MB/s and 160MB/s.

PhotoFast is currently licensed with Apple to make Apple accessories through the MFi Program, a privilege that could have been lost.
