Toshiba unveils an 18TB hard drive, joining the race to 30TB

Soon: Toshiba and Showa Denko have recently revealed their plans to improve the capacity of hard drives. Along with Western Digital and Seagate, they are betting on different magnetic recording technologies in hopes of launching 30TB drives in a few years.

Last week Toshiba sleepless its 18TB MN09 series NAS hard drive, which uses a new type of Microwave Assisted Magnetic Recording (MAMR) technology. Company Flux Control MAMR It allows for higher density on each hard drive platter. It has a speed of 7200 rpm, a buffer of 512 MB, and a transfer rate of 268 MiB / s.

Shortly after the presentation of the MN09, Showa Denko Announced is working with Toshiba on hard drives using microwave-assisted switching (MAS) MAMR to further increase capacity, eventually planning to reach 30TB. This technology uses a strong magnetic oscillation effect to record data in a much narrower track than previous forms of MAMR.

Digital west acclaimed MAMR in 2017, when it said it could have 40TB hard drives by 2025. Earlier this month, though the company’s CEO spoke about eventually reaching 30TB with density-increasing technologies like ePMR, SRM, and HAMR. He didn’t mention MAMR at all. WD already used OptiNAND, a new metadata storage method, to launch a 20TB drive last month.

Seagate launched a 20TB drive last year with HAMR and wants to hit 30TB by the middle of this decade. Seagate even believes it can hit 100 TB by 2030.
