The specs on this "Dell" laptop drive (like the 16MB cache) leads people to conclude that this is a rebadged Toshiba HDD2171 drive. The cheapest price for this drive on Pricegrabber is a little over $160. From the reviews I`ve read, this drive is extremely quiet and the ridiculously large 16MB cache should help with battery life. Search for 340-3965 or 340-3925 to get it. DELLHOME
