Towards an X10 of hard drive capacity?

Towards an X10 of hard drive capacity?

Recently, there was talk of NVMe 2.0 for mechanical drives. Other advances could further extend the interest of a technology that some people already saw as dead. The latest research has made it possible to increase the storage volume of hard disks tenfold without increasing their size. These advances are due in particular to the use of graphene disk platters. Disque dur Recent work has shown that the use of graphene provides a twofold reduction in friction and offers better protection against corrosion and wear than current state-of-the-art solutions. The use of this technology could therefore make it possible to significantly reduce the thickness of the plates. Finally, when graphene is combined with HAMR (heat assisted magnetic recording) technology, unprecedented data density is achieved, which implies a tenfold increase in the capacity of current hard disks. The work of the researchers therefore makes it possible to envisage spectacular gains in the capacities of mechanical disks in the relatively short term. It remains to be seen how the industry intends to take advantage of these advances and bring them to market. In addition to the hard disk in our PCs, the explosion in content/data consumption has led to strong growth in the data centre market in recent months.
