Hard drives with capacity of 100 TB in 2025



[ad_1]

Seagate plans to dramatically increase the capacity of hard drives. That is, the plan is to use HAMR technology (thermal magnetic assisted recording), which would increase the density of the input on the hard drive.

With this method, it is possible to achieve a dramatically higher register density than current and dominant PMR (perpendicular magnetic recording) technology. This is achieved thanks to the dramatic increase in heat in certain segments of the disc. The end result should be to increase the disk storage capacity or increase the input density.

This will increase the overall density and storage capacity of the disks. Heat is used to direct specific areas on the disc, which increases the recording density in a specific area. This increases the enrollment density in the main sectors of the disk, and the effect is similar to the periphery, although the efficiency is greater when segmenting sectors in the center of the hard disks.

The competition does not sleep, so Western Digital plans to do something similar using a MAMR (microwave-assisted magnetic recording) method, which would produce a similar effect by increasing the disk density on the disk in question.

Seagate announced that it expects to deliver the first HAMR-based discs by 2020. Initially, the 20TB capacity is announced, which does not sound as bombastic as 12TB discs are everyday, and Western Digital recently announced a 15 TB hard drive model! But after that, this method must have hard drives up to 36 TB in 2022, while in 2023 and 48 TB it can become standard.

Finally, if all goes well, by 2025 we should see the first hard drives of capacity – 100 TB! Ambitious plans, no doubt – let's see if they will come true. Seagate does not provide price discs. Of course, there is always the possibility that hard drives will replace flash memory by then, although it has been written for so long to become seriously skeptical …
