Seagate has given an update on its heat-assisted magnetic recording (HAMR) technology, revealing that it will release its first commercial hard drive using this recording method in Q3 2023, with a capacity of 32 TB. The new recording technology will allow for a relatively swift upgrade to a 40 TB capacity. Seagate says high-capacity HAMR hard drives will coexist with 24 TB and 28 TB models. The initial release will rely on a 10-platter platform, similar to one already in use by the company. These will be followed by 36 TB and 40 TB products, which will still use the same 10 disks and 20 heads technology.
