I have a 40gig 2.5" 9.5mm Toshiba Hard Drive that I took out from a laptop and replaced with a speedy 80gig 5400RPM. Now that I have an extra HD I was wondering if these drives are good a a boot volume for a desktop HTPC? Do these in general make less noise compared to their 3.5" cousins? Speed is not an issue of course, I just want a less noisy, less heat HD for my HTPC. I currently have what I consider a noisy Maxtor DiamondMax. Just wondering if I should bother getting a IDE adapter to make this desktop worthy!
