HDD capacity to increase to 60TB by 2028 thanks to technologies like HAMR

According to the forecast IEEE, to 2028 year hard drive capacity (HDD) will double to 60 TB, and their sales will grow to 359 million units к 2037 year, despite its growing popularity SSDOne of the main factors of this growth will be the introduction of new technologies, such as HAMR (thermal magnetic recording) from the company Seagate.

HAMR will be actively used in HDD production as early as 2024 year, which will lead to an increase in the capacity of hard drives. Analysts IEEE predict the release of models on 40 TB к 2025 year и 60 TB к 2028 year, but to 2037 year HDD capacity can reach 100 TB.

To achieve these figures, manufacturers will have to increase the recording density. For example, to create a disk with a capacity of 40 TB density will be required 2 TB/in²And for 60 TB - over 4 TB/in². TO 2037 year this figure will grow to 10 TB/in², which will require the use of new reading and writing technologies.

Despite the fact that the HDD spindle speed will remain at the level 7200 / min, increasing the recording density will have a positive effect on the speed of reading and writing. At the same time, IEEE predicts an increase in hard drive sales with 166 million в 2022 year to 208 million в 2028 year и 359 million в 2037 year, which is associated with the growing demand for capacious and affordable data storage solutions.
