Sry.. been a while since I've had to think about hard drive change so bit baffled with all the options!
I've currently got a 320gb Barracude so kinda feel this would be a good option as it's the same manufacturer.
Rig is pretty much used for gaming most of the time but I don't use a raid or anything. Plan is to get this drive, use Seagates software to transfer op system to it and then use my existing 320gb as storage/back up.
