Toshiba Electronics Europe GmbH announces the MG10 Series of capacity 20TB  HDDs with CMR .
It has a 10-disk helium-sealed design that leverages the company’s Flux Control Microwave Assisted Magnetic Recording (FC-MAMR) technology to boost storage capabilities.
With 11.1% more capacity than the firm’s prior 18TB model, 20TB MG10 Series HDDs are compatible with a range of applications and OSs, and are adapted to mixed random and sequential RW workloads in both cloud-scale and traditional data-centre use cases. These drives feature 7,200rpm performance, a 550TB/year workload rating , and a choice of SATA and SAS interfaces – all in a power-efficient helium-sealed 3.5-inch  form factor.
The 20TB MG10 Series further illustrates the company’s commitment to advancing HDD design to meet evolving needs for storage devices in cloud-scale servers, as well as object and file storage infrastructure. With its improved power efficiency and increased capacity, it helps cloud-scale infrastructure to advance storage density, thereby Capex and improving TCO. As data growth continues at an explosive pace, these HDDs 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 4Q22.
 Definition of capacity: 1TB=1 trillion bytes, but storage capacity actually available may vary, depending on operating environment and formatting. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
 Workload is a measure of data throughput in a year, and it is defined as the amount of data written, read or verified by commands from the host system.
 3.5-inch means the form factor of HDDs. It does not indicate a drive’s physical size.
