Seagate promised to release hard drives for 30 Tbyte during the year

Seagate revealed plans to market hard disks using second-generation magnetic recording technology: 30-Tbyte storage devices must be available within the next 12 months.

HAMR or Heat-Assisted Magnetic Recording methods suggest a new method of magnetic recording that reduces the size of the magnetic area storing one bit of information and increases the density of bits. During the recording process, a small laser diode installed at each head heats a small area of the plate for a short time. The heating-cooling process takes nanoseconds, while maintaining magnetic and thermal stability.

In accordance with the announced plans, Seagate will release second-generation HAMR discs with a capacity of 30 Tbytes no later than the middle of the following year. 40 Tbytes are expected to appear on the threshold of 2024 - 2025, and 50 Tbytes or more are planned to be stored by 2026.

True, as online sources point out, the cost of hard disks produced by second-generation HAMR technology will be very high, so their main application will be corporate class systems and data processing centres.

It is also noted that by the end of this year Seagate will have released 30-Tbyte server hard disks performed using traditional magnetic recording technology.
