MG09 Cloud-Scale Capacity HDDs Toshiba MG09 Cloud-Scale Capacity Hard Disk Drives (HDDs) provide up to 18TB of conventional magnetic recording (CMR) capacity. This massive 18TB CMR capacity is delivered using Toshiba’s innovative Flux Control Microwave-Assisted Magnetic Recording (FC-MAMR) technology. The 9-disk helium sealed design reduces aerodynamic drag to significantly lower the drive's operational power profile, which helps deliver critical TCO benefits for data centre infrastructures. The MG09 HDDs are available with SATA 6.0Gbit/s or 12.0Gbit/s SAS interface options. The industry-standard 3.5-inch (88.9mm) form factor provides 7200rpm performance and integrates easily into cloud-scale storage infrastructure, business-critical servers/storage, and file and object storage solutions. In addition, the MG09 HDDs are used in compliance data archives, data life-cycle management storage systems, data centre data protection, and data backup infrastructure.
