Seagate HAMRs out a roadmap for future hard drive recording tech

Seagate has set a course to deliver a 48TB disk drive in 2023 using its HAMR (heat-assisted magnetic recording) technology, doubling areal density every 30 months, meaning 100TB could be possible by 2025/26.

[...] Seagate will introduce its first HAMR drives in 2020. The chart [here], from an A3 Tech Live event in London, shows Seagate started developing its HAMR tech in 2016 and that a 20TB+ drive will be rolled out in 2020.

The last PMR drive appears in 2019/20 with 16TB capacity. Seagate's current highest-capacity drive is a 14TB Exos 3.5-inch product.

There is a forecast of areal density doubling every 2.5 years, and Seagate shows two other HAMR drive capacity points: 36TB in 2021/22 and 48TB in 2023/24. Capacity goes on increasing beyond 2025, with 100TB looking likely.

The firm makes the point that HAMR drives will be drop-in replacements for current PMR drives. Seagate will actually develop performance-optimised HAMR drives with MACH.2 multi-actuator technology – two read/write heads per platter – and capacity-optimised drives with shingled magnetic recording (SMR). These are shown in a [second chart].

    Seagate to Double HDD Speeds With Multi-Actuator Technology [soylentnews.org]

    Seagate's multi-actuator technology is a simple concept, and the idea certainly isn't new. In fact, the company has already developed drives with multiple actuators in the past, but they weren't economically viable due to higher component costs.

    Speeds are lagging significantly behind capacity so they needed to trot this out. Increasing sequential speeds can put HDDs in the ballpark of the cheapest SSDs (although they will always lose on random R/W and IOPS, and shingling, which will apparently be combined with HAMR in certain drives, hurts write speeds).
