Toshiba MG11ACA20TE 3.5" 20TB, 7200 RPM, 1024MB, 550 WRL, SATA III Hard Drive, Enterprise

The Toshiba MG11ACA20TE is an enterprise-class internal hard drive with a 20 TB storage capacity. It utilizes a standard 3.5-inch form factor and is engineered for continuous operation in demanding environments such as data centers and cloud-scale storage systems. The drive features a helium-sealed design and incorporates Flux Control Microwave-Assisted Magnetic Recording (FC-MAMR) technology. These elements contribute to its high storage density and operational efficiency under constant use.

Performance is handled by a 7200 RPM spindle speed and a SATA 6 Gbit/s interface, which is supported by a large 1024 MB cache buffer to facilitate data handling. The drive is rated for a workload of up to 550 TB per year and has a Mean Time Between Failures (MTBF) of 2.5 million hours, indicating its suitability for high-intensity storage tasks. It is built for 24x7 operational readiness in multi-drive server and storage systems. This combination of capacity and reliability metrics makes it a component for building large-scale storage infrastructure.
