So a company is claiming to make a flash memory module that you can swap out with the built-in storage on your MacBook Air, giving you 256GB of storage. They also give you a USB 3.0 housing for your chip that you take out. Sounds pretty neat, no pricing yet (that is going to determine if it is worth it).
As a side note I busted off a connector on my Wife’s MacBook Pro last night swapping the HD – upgrades like these are not for those that can’t afford to have to replace expensive parts.
