An ongoing teardown of the new 11-inch MacBook Air by iFixit has discovered extra details beyond just what Apple showed during its own keynote. The ultraportable's SSD was already known to be custom since none take up its very narrow shape, but the 64GB example here is now known to be entirely Toshiba-derived and uses the Japanese firm's memory controller and four 16GB chips from the same firm. It won't be user-replaceable but, at half the thickness and less overall area, is key to the system's thin design.
