The 60GB in my laptop is getting a bit cramped, but I have always had the intention of replacing it. I wouldn't mind a faster drive than the hts541060g9sa00 in my laptop now. Power is not a huge issue, I didn't buy it for battery life. Is the performance of a 7200rpm drive worth it? Is there a particular make/model of drive that I'd be better off with at 5400rpm? I've seen some fairly large drives at 5400rpm at very low prices, but I am concerned about performance.
