I currently have a 7200 rpm hard drive with 1TB, I'm also low on the budget and I can't really get an ssd with 1TB but is a Solid State Hard Drive better? They seem to be pretty cheap and has a larger capacity, they are also faster than hard drive because they are a mix of hdd and ssd. So are SSHD's a direct upgrade from the 7.2k rpm Hard drive but cheaper?
