Seagate plans to release 22, 24 and 30TB HDDs this year. The latter should appear in the third quarter and contain the hamr technology. It is not yet known how many disk heads it will receive.
The 22 and 24TB hard disks should appear in the first or second quarter and use conventional/perpendicular magnetic recording– en shingled magnetic recording technology. These also contain ten disk heads in a housing of 2.2TB each.
Less information has been disclosed about the 30TB hdd, except that it uses heat assisted magnetic recording. This technology was developed by Seagate and uses lasers to increase the capacity of hard drives. According to the manufacturer’s CEO, Dave Mosley, development of these hamr hdds is moving faster than expected, allowing Seagate to release them a little ahead of schedule. However, a specific date is not mentioned. Mosley does report that a limited amount of these hard drives will initially be produced. As manufacturing costs are reduced and hamr revenues can be increased, circulation will steadily increase. Mosley expects that to happen within two years.
Based on Seagate’s roadmap, HDDs in excess of 40TB are planned to be released between 2024 and 2025. The first hard disk with a capacity of more than 50TB should appear in 2026. Last year the smr- 22TB HDDs have already been delivered to a select number of major customers.
