Hello everyone. I have recently built a new computer and am looking to upgrade my weakest link, which is my HDD. I am currently using the one that came with my Inspirion 530s. I know little about Hard Drives so my question is this. I can't afford an SSD, so for between 50-75 dollars what is a good HDD to get? I did ask a friend and he said I should find one with a 64 MB cache since I am running Windows 7 64 bit, does it reall matter if I use a 16, 32, or 64 mb cache hard drive? I am sure it does but I hope to gain some knowledge on the matter. Thanks in advance for your replies. If you need more info about my computer let me know, I am not sure what kind of things you need to know when talking about upgrading a HDD.
