the launch of a 20TB high-capacity conventional magnetic recording (CMR) mechanical hard drive, which belongs to the MG10 series. It adopts a 10-disk helium-filled sealed design and uses Toshiba’s FC-MAMR ( Flux Control Microwave Assisted Magnetic Recording) technology to improve storage capacity. It can reduce capital expenditures and optimize TCO (total cost of ownership) by helping to increase storage density in cloud-scale infrastructure.
Previously, the largest capacity mechanical hard drive sold by Toshiba was 18TB, such as the N300 Pro and X300 Pro series hard drives released earlier this year, but competitors Seagate and Western Digital have released models of 20TB or more as early as last year. The new 20TB model comes in a 3.5-inch form factor with an 11.11% increase in capacity compared to the 18TB model, with a rotational speed of 7200rpm, a rated workload of 550TB/year, optional SATA and SAS interfaces, and an energy-efficient helium seal.
Toshiba said that the MG10 series 20TB models have good compatibility with many applications and operating systems, and can adapt to mixed workloads of random read and write and sequential read and write, suitable for cloud-scale and traditional data center applications. At the same time, it fulfills Toshiba’s commitment to advance the design of mechanical hard disk drives to meet the growing demand for storage devices in cloud-scale servers and object and file storage infrastructures.
