How can I tell which USB memory stick will be fast enough to run OS X Lion from. The HDD on my rev A MacBook Air is showing up in disk utility in red, it says this disk has a fault which cannot be repaired, please backup a seek assistance, though it has been showing this for over a year I assume it will go pop eventually. I have tried running lion from a portable HDD but having this hanging off the side it loses portability ,and this drains the battery, due to age I think putting a new drive in is more hassle than its worth, and finding a SSD at a reasonable price seems hit and miss, whether the one you order will work with a rev A . I have tried 1 or 2 memory sticks they have worked but been quite laggy due to speed. Any advice would be greatly appreciated.
