HAMR HDDs To Debut At 4TB Capacity But Reach 100TB By 2025

Heat-assisted magnetic recording (HAMR) is a novel process in which a small laser is used to apply heat to a disk so more data can be written to a standard platter. Some thought this was implausible, but Seagate says they will be introducing them next year for testing. Do you think mechanical hard drives are going to stay relevant thanks to these advancements, or will improvements in SSD capacity make them obsolete?

It seems that shipments of HAMR-based hard drives will start in 2018 after the tests started in 2016 probably end in 2017 and demonstrate whether HAMR tech is ready for mass production or not. To beat the rapid advancement of SSDs driven forward by Samsung, Seagate plans to make the new drives available only to select cloud and hyperscale datacenter customers, and only after that, the technology will move to the wide spread consumer market.
