In a guest post, Seagate CTO Mark Re gave Backblaze an inside look at how company engineers are developing HAMR technology to dramatically increase hard drive capacity beginning in 2018. Although hard work remains, they believe the technology is nearly ready for commercialization.



Current projections are that HAMR can achieve 5 Tbpsi (Terabits per square inch) on conventional HAMR media, and in the future will be able to achieve 10 Tbpsi or higher with bit patterned media (in which discrete dots are predefined on the media in regular, efficient, very dense patterns). These technologies will enable hard drives with capacities higher than 100 TB before 2030.
