I never feel like I have enough hard drive space. My Mac Mini has a 100GB, my MCE has 160GB, (used to have another 250gb but it died) and my Mac Book Pro has 120GB. I also have a few external drives I am moving data around too.
The problem with my laptop hard drives is that they are too slow, man 5400rpm really feels like it is holding me back. Maybe it’s just in my head, but everytime there is a delay I can blame on my disc access speed, I do. I would love to buy a bigger/faster hard drive for my MBP, but they don’t really make one. Every few months I look for say a 160gb 7200rpm 2.5 drive and no dice. Why is this? What does speed have to do with size, why can’t they make a 160gb 7200rpm laptop drive? You almost never see this in desktop drives, when the latest large capacity drive comes out it is almost always available in a 7200rpm variety. I guess the same can’t be said for 15000rpm, but still, I don’t get it.
