Hi, I am about to buy my external hard drive for time machine for my MacBook Air.. I noticed that some disk drives are faster than 4200rpm.. Will i have problems with these drive with my MBA?
 
see, the macbook air's harddrive is tinier than the one in macbooks, so it does not need to rotate as fast.

hope that makes sense.
