Seagate Drives Hit 1 Terabit Per Square Inch
To have made such a big advance in drive density, Seagate incorporated a research called heat-assisted magnetic recording. The size of each magnetic bit in a hard drive dictates its size – these bits can only be made so small previously the magnetism of other bits begins to take effect. HAMR bits are made of compounds that can withstanding furthermore miniaturization. Fujitsu developed HAMR in 2006, and the system adds a laser to the hard drive head. The drive head seeks as normal, nevertheless when it is time for data to be written, the laser comes on.
Still, one might wonder what the point of local storage will become, as cloud-based storage and computing advances. Nevertheless 60TB local drives, coupled with 100Mbps internet connections might as well make the idea of a cloud a bit pointless as then. Although, the latter is unlikely, as smartphones and tablets with flash memory, in tandem with cloud drives might in the long run make mechanical hard drives obsolete for typical computing.
