Toshiba Announces 20TB MG10 Series Hard Disk Drives
Kawasaki, Japan—Toshiba Electronic Devices & Storage Corporation (Toshiba）has announced the launch of MG10 Series, a massive capacity 20TB[1] HDD with conventional magnetic recording (CMR) . The 20TB MG10 Series has a 10-disk helium-sealed design that leverages Toshiba’s innovative Flux Control Microwave Assisted Magnetic Recording (FC-MAMR™) technology to boost storage capabilities.
With 11.1% more capacity than Toshiba’s prior 18TB model, 20TB MG10 Series are compatible with the widest range of applications and operating systems, and are adapted to mixed random and sequential read and write workloads in both cloud-scale and traditional data-center use cases. The drive features 7,200rpm performance, a 550TB per year workload rating[2], and a choice of SATA and SAS interfaces—all in a power-efficient helium-sealed, industry-standard 3.5-inch[3] form factor.
The 20TB MG10 Series further illustrates Toshiba’s commitment to advancing HDD design to meet evolving needs for storage devices in cloud-scale servers and object and file storage infrastructure. With its improved power efficiency and increased capacity, the 20TB MG10 Series helps cloud-scale infrastructure to advance storage density, thereby reducing capex and improving total cost of ownership (TCO). As data growth continues at an explosive pace, the advanced 20TB MG10 Series with FC-MAMR™ technology will help cloud-scale service providers and storage solution designers to achieve higher storage densities for cloud, hybrid-cloud and on-premises rack-scale storage.
Sample shipments of 20TB MG10 Series HDD to customers are expected to start in the fourth calendar quarter of this year. 
MG10 Series
The MG10 Series features Toshiba’s fourth-generation, 10-disk Helium-sealed design to advance Conventional Magnetic Recording (CMR) density to 2TB per disk, achieving a total capacity up to 20TB.The industry-standard 3.5-inch form-factor provides 7200rpm performance, and integrates easily into cloud-scale storage infrastructure, business-critical servers and storage, and File and Object storage solutions.
The massive 20TB CMR capacity is delivered using Toshiba’s innovative Flux Control Microwave Assisted Magnetic Recording (FC-MAMR™) technology. These advances help the MG10 Series to achieve optimum storage capacity and application compatibility, with unsurpassed data reliability. Available with a SATA 6.0Gbit/s interface, the MG10 Series models integrate easily into standard 3.5-inch drive bays to help reduce the footprint and operational burden of cloud-scale storage infrastructure, File and Object storage systems, and business critical servers and storage systems.
