Record magnetic recording density 421 gbit/inch**2

Tweet Seagate expects drive capacity to increase to 275 Gbytes for 1- and 1.8-inch consumer drives, 500 Gbytes for 2.5-inch notebook drives and nearly 2.5 Tbytes for 3.5-inch desktop drives based on the new higher density capability.

Kryder said heat-assisted magnetic recording (HAMR) and bit-patterned media techniques can boost storage capacities to reach or exceed 50 terabits/ inch**2. Drives with those capacities would be have over 200 Tbytes of storage for a 3.5 inch drive.
