We've come a long way from when hard drives were measured in megabytes, and then gigabytes. Today the biggest drives are measured in terabytes, and while that probably won't change for a long time to come -- we're not quite on the cusp of the petabyte era -- owning massive capacity hard drives that dwarf today's offerings could be a commonplace practice in the next few years if Seagate's heat-assisted magnetic recording (HAMR) technology lives up to the hype.
Though HAMR was developed by Seagate, Western Digital thinks it can achieve fives times the areal density of current drives using its own implementation of the technology, TechSpot reports. Well on its way to implementing HAMR in consumer drives, Western Digital recently demonstrated the tech at a Chinese trade show.
HAMR is unique in that it temporarily heats up the HDD's surface with a laser while the magnetic head records data. This causes the bits to shrink, thereby significantly increasing area density. To put the technology into perspective, today's drives top out with an areal density of 750 gigabits per inch. HAMR could raise the ceiling to over 4 terabits per inch.
Western Digital hasn't made any storage claims with HAMR at the helm, though Seagate has previously said its technology could lead to 60TB desktop hard drives by 2016.
