Seagate is working on 30TB HDDs, 50 TB in 5 years and 100 TB by 2030


Recommended Posts


Although there is no official release date for the 30TB Hamr (Heat Assisted Magnetic Recording) HDD, it is projected to arrive in 2023 or 2024, several years before the objective of a 50TB drive, which is set for 2026. These limited-edition hamr hard drives are meant particularly for "primary consumers" who want to become acquainted with the latest technologies. With the 30TB drive, the business is one step closer to achieving its 10-year objective of creating 100TB drives.

A while ago researchers have managed to increase the achievable data density tenfold with the help of graphene. Hard drives use a carbon-based overcoat to protect the platter from read and write heads and other factors. To increase storage capacity, manufacturers have reduced the space between the head and the platters. Today it is about 3 nanometers thick, which has increased the density to about 1 TB per square inch. The researchers replaced a coating with a variant of graphene, containing one to four layers of the material. After measuring corrosion, thermal stability, surface smoothness and lubricant handling, they concluded that graphene reduces friction by a factor of two and causes two and a half times less corrosion. Hamr heats the iron-platinum alloy platters to high temperatures that regular coatings cannot handle. Graphene in combination with hamr should be able to lead to a data density of about 10 TB per square inch.

I remember hearing about graphene being holy grail of tech all the time when I was younger. Cool to see it making it's way into something tangible.

Great read. The HDD is certainly nowhere near dead. With the help of HAMR and introduction of Graphene tech, the storage capacities possible will keep growing. All while within reason still being the cheaper technology for mass storage.


Theres reasons why even performance nerds like us still use HDD's in a NAS solution over SSD....its cheaper and storage capacities being far more realistic. You can get some great enterprise drives for fairly cheap these days that perform very well. Plus you can put install lower capacity SSD/NVMe into a NAS for caching and data tiering to further enhance performance.


In my main NAS I have 2x Seagate Exos HDD's combined with 2x Sandisk  Ultra SSD's that take care of caching and data tiering.

Hopefully it will lead to that final nail in sata's coffin.

I think Sata will be with us for a while just for the sakes of compatibility.
