Earlier this year Showa Denko K.K., an independent producer of platters for hard disk drives, announced its first eighth-generation perpendicular magnetic recording platters for HDDs. The eighth-gen media has unprecedented areal density and is designed for 2.5” hard drives. Capacity of the new platter is 750GB, which allows to build dual-platter HDDs with 1.5TB capacity as well as triple-platter hard drives with 2.25TB capacity.
Showa Denko also intends to accelerate its development of next generation 2.5” HD media with storage capacity of 1TB. It is unclear when exactly such platters emerge on the market, but Seagate could use them to build dual-platter 2TB HDDs as well as triple-platter 3TB HDDs for notebooks.
