Seagate this week revealed some of the details concerning its heat assisted magnetic recording (HAMR) technology roadmap. The company's first HAMR hard drive will feature a 32TB capacity. Meanwhile, the 32TB drive exists alongside Seagate's 24TB HDD, the company's last drive based on perpendicular magnetic recording.

Seagate's first HAMR HDD will use ten 3.2TB platters and will thus offer a capacity of 32TB. The 10-disk platform — which is already used for Seagate's high-capacity PMR drives — will continue to be used for a while as the company's following HAMR drive will feature a 36TB capacity and will pack 3.6TB platters. Next up will be 40TB with 4TB media and the company is already mulling 50TB hard drives featuring 5TB disks that already exist in the lab. The company did not reveal launch timeframes for its HAMR drives, but it once said that they were set to be released in Q3 2023.
