TDK breaks the Hard Drive density limit, could go on to develop super-sized storage

While the old-fashioned hard drive isn't as fast or slender as an SSD, it can still lord its greater capacities and cheaper price over its upstart rival. TDK thinks it's extended the mediums lead in that area by tweaking the magnetic heads and recording medium of the hardware -- increasing the areal density of a unit to 1.5 TB per square inch. It means that we could see 1TB platters arriving in 2.5-inch laptop drives and 2TB platters in desktop modules, meaning even your commuting machine can store all of your heftiest data with ease.
