The new technology HDMR of Western Digital (WD) could allow hard drives that exceed 100 TB in the future.
HDMR of Western Digital promises hard drives of more than 100 TB
Western Digital is working on a new storage technology called HDMR (Magnetic recording for heat points), which would be the evolution of technology Hamr (heat assisted magnetic recording).
Currently, technology Hamr of Western Digital will allow for hard drives with a capacity between 80 TB and 100 TB Storage for the year 2030, which would be an impressive advance in this field, but Western Digital knows that it will need a new technology to continue increasing the storage capabilities of its magnetic recording units.
We recommend our guide on the best hard drives in the market
HDMR is a recording technology that implies heat -assisted writing with bits patterns (BPM) that promise to reach area densities of around 8 TB/inch^2 and more, to allow hard discs of 10 dishes with 120 TB or more capacities. This technology is expected to be quite expensive, since discs with bits patterns should be physically designed by lithography or engraved equipment in white rooms, so they would not have a process similar to that of current hard drives. These bits patterns would replace the granular magnetic lining that currently use hard drives.
The combination of physical insulation of bits (BPM) with energy-assisted writing (HAMR) in HDMR can lead to impressive capabilities, although with a cost higher than traditional hard drives, so this must evolve so that the costs do not Be too high. However, we do not expect to see HDMR hard drives until after 2030. We will keep you aware of all the news.
