Toshiba at CES 2019: World’s First 16 TB TDMR HDD Debuts
 

Toshiba has announced the industry’s first hard drive featuring a 16 TB capacity. The MG08-series HDDs are designed for nearline applications and use two-dimensional magnetic recording (TDMR) technology, therefore offering consistent and predictable performance.

Toshiba’s MG08 3.5-inch helium-filled hard drives rely on nine 1.7 TB PMR platters developed by Showa Denko K.K. (SDK) as well as 18 reader/writer TDMR heads designed by TDK. The HDD features a 7200 RPM spindle speed, a 512 MB DRAM buffer, and a SATA 6 Gbps or SAS 12 Gbps interface (depending on the model). Since the MG08 HDDs are aimed at nearline applications that use hundreds of hard drives per rack and are subject to severe vibrations, the HDDs feature top and bottom attached motors, RVFF as well as environmental sensors and other innovations designed to improve reliability and ensure consistent performance.
