Hard disks with a capacity of 100 TB by 2025


Seagate plans to dramatically increase the capacity of hard drives. The plan intends to use HAMR technology (heat-supported magnetic recording) to increase the input density on the hard disk.

This method makes it possible to achieve a dramatically higher enumeration density in conjunction with the current and predominant PMR technology (rectangular magnetic recording). This is achieved by a dramatic increase in heat in some segments of the disk. The end result should be to increase the capacity of the discs or increase the input density.

This will increase the overall density and capacity of the disks. Heat is used to target specific areas on a disk, which then increases the density of the entry in a particular area. This increases the density of enrollment in the main disk sectors, and the effect is similar to the margin, although efficiency is greater when targeting sectors in the center of hard drives.

The competition does not sleep, so it is planned that Western Digital will do something similar using the MAMR method (microwave assisted magnetic recording), which would actually have a similar effect in increasing the disk density on the disk concerned.

Seagate announced that it expects to deliver first plates based on HAMR technology in 2020. At the beginning, the predicted capacity is 20 TB, which does not seem so bombastic, as 12 TB disks are everyday and that Western Digital recently announced the 15 TB hard drive! After that, this method should have hard drives of capacity up to 36 TB by 2022, while in 2023 and 48 TB it could become standard.

Finally, if everything goes smoothly, in 2025 we will see the first hard drives of capacity – 100 TB! Ambitious plans, no doubt – we will see if they will come true. Seagate does not offer price drives. Of course, there is always the possibility that hard drives will replace flash memory by then, although it has been written so long that it becomes seriously skeptical …
