The storage capacities of HDDs
companies have not finished taking off with the adoption of the HAMR.
On machines intended for individuals, hard drives have virtually disappeared. Platters and read heads gave way to SSDs and their flash memory. In business, it’s a different story, as Toshiba in turn proves to us.
30 TB in 2023, 40 TB in 2026
After Seagate and Western Digital, the Japanese publishes its roadmap to highlight the progression of storage capacities, an area in which SSDs are still largely overtaken by “traditional” units.
Currently, Toshiba relies on FC-MAMR technology (Flux-Controlled Microwave-Assisted Magnetic Recording) to reach 18 or 20 TB and it plans to increase its capacity to 26 TB this year. However, the Japanese will then switch to MAS-MAMR (Microwave-Assisted Switching Microwave-Assisted Magnetic Recording).
This technology should allow him, from 2023, to market 30 TB hard drives and he is even considering 40 TB by 2026. On this last point, things are a little more vague, however, insofar as he underlines the arrival of the HAMR technique (Heat Assisted Magnetic Recording), also mentioned by its main competitors.
Thanks to the HAMR, Western Digital is considering hard drives of more than 30 TB from 2025 when Seagate does not hesitate to mention 120 TB of capacity by 2030. In order to support the increase in capacity of its hard drives , Seagate mentions the use of Mach.2 technology and its second actuator. Not so at Toshiba.
