As it's getting increasingly difficult to raise the record density of platters (see "Digest 2004"), the new 400 GB models from Hitachi are manufactured using time-proven 80 GB platters, by packing as much as five such platters (and 10 heads) into the standard 3.5-inch housing! So they got back to the long forgotten old solution — long before this model, famous DTLAs and still earlier IBM disks regularly featured 5 platters in senior desktop hard disks — Deskstar 75GXP, 34GXP/37GP, 22GXP/25GP and 14GXP/16GP series.
