Unless you are buying a Seagate DB 35 drive which is tuned for DVR's. Western Digitals with the part number ending in JB such as the WD3200JB are tuned for DVR's while those ending in BB are tuned for speed and may no last as long. I just bought a Diamond MAX 21 which is made by Seagate, the drive is quiet and only $99.99 for 500 GB.
