As solid state drives are getting more and more cheaper as time passes by, not to mention that their capacity size has increased tremendously, Helium-based mechanical hard disks will push the barriers of insurmountable levels of storage.
That being said, it will not be long till we start to see 18TB hard drives in the market.
According to a storage research firm by the name of TrendFocus, hard drive manufacturers will be able to dispense with disk platter separator components, allowing them to squeeze more storage platters into a 3.5-inch enclosure.
While this all looks very exciting for desktop and server-based storage hard drives, what about those drives that are fit into mobile machines such as notebooks. Currently, notebooks are only able to accommodate 2.5-inch hard drives, and honestly, we do not see that changing at the moment due to their thickness.
It is relatively difficult to store a large amount of storage platters inside smaller form factors due to space limitations but overtime, we expect that to change with the arrival of 18TB hard drives.
Hard drives are currently using a perpendicular magnetic recording tech, but manufacturers switching to shingled magnetic recording will allow them to increase the drive’s overall capacity, with 18TB storage peripherals expected to arrive during 2017.
