as the title says, i am in need of a second hard drive. I have a 74gb WD raptor 10k rpm that is very full. I will keep my games on it and move everything else to the other drive. I am looking to spend between 50-75 dollars and have no need for massive amounts of space. i have been led to believe that a 32 mb cache is the way to go, even though i do not know what a cache is heh. I want at least 7200 rpm and would like your suggestions! thanks alot in advance!
