Hungry for more hard drive space to download all the episodes of the Tech-Stew Podcast plus your Blu-ray movies?  Well, hang tight, because Seagate has an even larger solution than before.  Seagate announced Monday that they are the first hard drive manufacturer to reach a storage density of 1 terabit per square inch.  They accomplished this through heat-assisted magnetic recording (HAMR), instead of the usual Perpendicular Magnetic Recording (PMR) method.  This should allow 60 TB capacities within 10 years on a single drive.  Imagine the RAID array possibilities with this capacity.

The existing density areal maximum was 620 gigabits per square inch.  Seagate has stated the first generation drives will likely double the capacities of the largest 3.5 and 2.5" drives in the near future to 6 TB and 2 TB.  The theoretical areal density limit ranges from 5 to 10 TB per square inch, so capacities should range from 30 TB to 60 TB for 3.5-inch drives, while 10 TB to 20 TB for 2.5-inch drives.
