Seagate 30 TB + HAMR HDDs To Ship By Mid-2023

Seagate is trying to increase the density of bits packed into the surface area per square inch so that more data bits (particles) can be put into the platter in order to increase the capacity of the HDD. The more bits you have, the more data you can store. Seagate has already sold a 20TB HDD with a surface density of about 1.116Tb per square inch, but technically it has achieved a surface density of about 2.6Tb per square inch, 2030. It has been proven that it can grow to 6 Tb per square inch, which will achieve 100 TB by the year.
HAMR helps to achieve this density. Normally, as the density increases, the distance between particles decreases, and the magnetism of each particle may affect the magnetic direction of surrounding particles. This causes problems with particle stability at room temperature, but using a new platter material eliminates the problem. However, there is another problem of how to change the magnetic direction of the particles stabilized by such platters and how to write the data.
HAMR, which solves this problem, inverts the magnetic polarity of the bit by heating a specific area with a laser, making it possible to write data. It is said that each bit is heated and cooled in 1 nanosecond, and it is explained that the laser does not affect the temperature of the drive or the temperature, stability and reliability of the entire media. ..
Seagate announced that it will release a 30TB or larger HDD equipped with this HAMR in 2023, but at this point it will not be shipped to general users, but first to only some customers in the data center market. It is planned to be.
Seagate's roadmap plans to introduce HDDs of 40TB or more in the latter half of 2024 and HDDs of 50TB or more in 2026.
