I want to get my sister and I a new hard drive because there is very little space on it. Either a 160 or 320 gb hard drive. I was looking around on newegg and found one that i thought would have worked well but one of the reviews said it should just be used as a storage drive because it only had 8mb cache which led to a slower start up. This computer is running xp and i wasnt sure if a hdd with 16mb cache would perform that much better than one with 8mb.
