Toshiba unveils an 18TB laborious drive, becoming a member of the race to 30TB


Briefly: Toshiba and Showa Denko have lately unveiled their plans for advancing laborious disc drive capability. Together with Western Digital and Seagate, they’re betting on totally different magnetic recording applied sciences in hopes of releasing 30TB drives in a number of years.

Final week Toshiba unveiled its 18TB MN09 sequence NAS laborious drive, which makes use of a brand new type of Microwave-Assisted Magnetic Recording (MAMR) know-how. The corporate’s Flux Management MAMR permits for larger density on every laborious drive platter. It has a velocity of 7200rpm, a 512MB buffer, and a switch charge of 268 MiB/s.

Quickly after the MN09’s unveiling, Showa Denko introduced it’s working with Toshiba on laborious drives utilizing Microwave-Assisted Switching (MAS) MAMR to extend capability additional, finally planning to succeed in 30TB. This know-how makes use of a robust magnetic oscillation impact to file knowledge on a a lot narrower observe than earlier types of MAMR.

Western Digital hailed MAMR in 2017, when it stated it may have 40TB laborious drives by 2025. Earlier this month although the corporate’s CEO spoke about finally reaching 30TB with density-increasing applied sciences like ePMR, SRM, and HAMR. He didn’t point out MAMR in any respect. WD already used OptiNAND, a brand new metadata storage methodology, to launch a 20TB drive final month.

Seagate launched a 20TB drive final yr utilizing HAMR and desires to succeed in 30TB by the center of this decade. Seagate even thinks it could hit 100TB by 2030.
