Seagate introduces the roadmap for the future development of 120TB hard drives, HAMR and Mach.2 technologies will become standard

Recently, Seagate introduced its product and technology roadmap. It is expected to launch a 50TB hard drive before 2026, a 100TB hard drive before 2030, and a 120TB hard drive at the beginning of the next decade. In order to achieve the goal of increasing capacity, Seagate will adopt new magnetic recording technology to ensure the high performance of future hard drives.

Seagate plans to use multi-drive (Mach.2) technology more widely. This technology will double the performance of hard drives and is likely to become the standard configuration of the product line.

According to TomsHardware, Seagate is currently selling hard drives based on heat-assisted magnetic recording (HAMR) technology to designated customers as part of its Lyve storage system. Heat-assisted magnetic recording can enable Seagate to increase disk density at a compound annual growth rate of 20%, which means that hard disk capacity will take even greater steps forward. At present, the capacity is increased by 1TB or 2TB, and in the future, it will be increased by 4TB, 6TB or even 10TB.

Seagate has made relevant preparations to build 9 40TB hard drives. The track density of the disc media will be increased to about 2600Gb/in2 (2.6Tb/in2), but it still needs to improve the head, main control chip and other supporting parts, 40TB The hard drive will be ready in three to five years. HAMR technology can achieve 80TB to 100TB capacity hard drives, but when the track density is 5-7Tb/in2, the magnetic particles will become very small and the track will also become very narrow. Before the 8Tb/inch2 track, density BPM technology appears, there will be a short transition period for the ordered magnetic particle film.

In addition to capacity, speed is also important for large-capacity hard drives, especially in data center applications, where continuous read/write speeds and random IOPS performance per TB are also important. If the IOPS per terabyte drops, the data center will choose some way to alleviate this situation, which requires additional investment.

The current very straightforward method is the application of multi-drive technology, which can double the performance of hard disk IOPS and reduce latency.

Seagate said that mechanical hard drives and SSDs will work together for a long time in the data center, and it is not worried that mechanical hard drives will be replaced by SSDs.
