Toshiba MG09 Cloud-Scale 12TB 3.5" Enterprise / NAS SATA 7200 RPM Hard Drive

12TB Toshiba Enterprise MG09ACA12TE

The Toshiba MG09ACA14TE 12TB Enterprise Hard Drive is a high-capacity, data-centre-ready storage solution engineered for 24/7 operation in cloud-scale storage infrastructure, enterprise servers and mission-critical storage arrays. Designed to meet the demands of modern data centre workloads, Toshiba's MG09 Series - a family of cloud-scale high capacity HDDs - provide massive storage density alongside industry-leading reliability and energy-efficient performance, featuring advanced Conventional Magnetic Recording (CMR) and 9-disk helium-sealed design.

Enterprise-Grade Design for Cloud-Scale Storage

Built on Toshiba's Flux Control Microwave-Assisted Magnetic Recording (FC-MAMR) technology and sealed with helium to reduce aerodynamic drag, the MG09ACA12TE delivers superior storage density while lowering operational power consumption for a lower total cost of ownership. Its 3.5-inch form factor and 7200RPM rotational speed make it ideal for integration into standard enterprise server bays and large storage arrays, supporting consistent performance and reliability in always-on environments. With a workload rating of up to 550TB transferred per year, this drive is engineered for continuous use in cloud and rack-scale deployments.

High Capacity and Balanced Performance

The MG09ACA12TE offers 14 terabytes of formatted storage, providing extensive capacity for large datasets, backups, archives and object-based storage systems. Its 512 MiB cache buffer helps accelerate data access and improves sustained throughput, with typical internal data rates of up to approximately 268 MiB/s - enabling efficient handling of sequential workloads common in enterprise applications.

Robust Reliability and Power Efficiency

Enterprise reliability is central to the MG09 Series, with the MG09ACA12TE rated for a mean time between failures (MTBF) of 2.5 million hours and advanced features such as Toshiba Persistent Write Cache Technology to help protect data during sudden power loss events. Its helium-sealed design and optimised mechanical architecture deliver both high reliability and low power consumption, measuring around 3.3W at idle and approximately 7.43W under active read/write workload.

Engineered for Enterprise Workloads

This drive includes enterprise-oriented features such as rotational vibration (RV) sensors, robust shock and vibration tolerance, and broad environmental endurance - making it well suited for demanding datacentre environments. With support for enterprise seismic and operational vibration conditions, it maintains stability when deployed in dense rack configurations or multi-drive systems.

Applications and Use Cases

The Toshiba MG09ACA12TE is ideal for a wide range of enterprise storage scenarios, including cloud-scale storage clusters, software-defined storage, file and object infrastructure, tiered storage solutions, compliance-level data archives, and data protection/back-up infrastructures where capacity, endurance, and reliability are paramount.
