I know Mountain Lion added the ability to use multiple HDs simultaneously (I have done this). As it stands, it just rotates among the different HDs each time it does a backup. Is there a way to have OSX combine two HDs to make a 'virtual' bigger HD?


The reason I ask this is because my existing iMac has a 1TB internal hard drive. I have two external LaCie drives of 2 TB each that I use for Time Machine. I'm planning on getting one of the new iMacs and custom-ordering it with a 3TB internal drive. Obviously a 2TB drive won't fit, but if OSX can combine the two HDs virtually, it'll end up with a 4TB volume, right? Can it do that?
