I have an early 2011 15" mbp. I always only had a 500gb hd in it. Recently, its performances have starting becoming inadequate, so I switched its 4gb of ram for 16gb & its hard drive for a 480gb ssd. It is a night and day difference that should be enough to make me keep it one more year at least. The only really weak part now is the graphic card that may be too weak to support an high size high resolution screen.
