Hello, I'm new to the ssd market and I have some questions that I hope you guys can answer for me. I plan on installing dual drives, ssd in the main bay and my old hdd in the optical drive. I've done some research on these forums and I'm leaner towards a Crucial m4 6G. 1. What size would be adequate if I had the hard drive for storage? 2. Where can I purchase the other tools I need to install my old hard drive and how would I do it?
