Well, I just bought myself a stock HR10-250 on eBay. I figured it would be a good idea to start it's new life with us with a new hard drive, and while I'm doing that I thought I'd bump it up to a nice 500GB. I was looking at the Seagate Barracuda, but I can get a DB35 Series 7200.2 or 3 for about $60 more than a Barracuda from CDW. These are supposed to be made for DVRs, does anyone have any experience with them? Is there a real difference? This going to be the new, main family Tivo, so stability and longevity are key- I don't mind spending the extra if it's going to make a difference. And if it is, which one- the 7200.2 or the 7200.3?
