Hard disk capacity of 100 TB by 2025



[ad_1]

Seagate plans to dramatically increase the capacity of hard drives. Namely, the plan is to use the HAMR (Hot Magnetic Record) technology, which would increase the recording density on the hard disk.

This method makes it possible to achieve dramatically higher receiving densities in connection with the current and prevailing PMR (Perpendicular Magnetic Recording) technology. This is due to the dramatic increase in heat in some segments of the drive. The end result is to increase the storage capacity of the drives or increase the recording density.

This will increase the disk's total density and storage capacity. Heat is used to target specific disk space, which then increases the density of registration in a specific area. This increases the recording density in the main disk sectors, and the effect is similar to the peripheral, although the efficiency is higher, targeting the sectors in the hard disk center.

Competition is not able to sleep, so Western Digital intends to do something similar using MAMR (microwave magnetic recording) method, which would actually produce a similar effect by increasing the disk's density on the disc.

Seagate announced plans to ship its first discs based on HAMR technology in 2020. Initially, the volume of 20 TB has been announced, which seems to be so sad considering that 12 TB drives are routine and that Western Digital has recently announced a 15 TB hard drive model! But then this method should have hard disks with capacity up to 36 TB by 2022, but in 2023 and 48 TB it could become the standard.

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