My 250GB HD in my 2009 MBP decided to crap out. I've got a Time Machine back-up. Whew. Here's my problem: I was thinking about getting an Intel 320 SSD (160GB) and later swapping out my optical drive for an OptiBay with a standard (bigger) HD. Before I buy the SSD, will a Time Machine restore work on a smaller HD? Or do I have to buy both HDs now, restore to bigger HD, then do a fresh Lion install on the SSD?
