Toshiba MG08SDA400E 3.5" 4TB, 7200 RPM, 256MB, 550 WRL, SAS Hard Drive, Enterprise

The Toshiba MG08SDA400E is a 3.5-inch internal hard drive with a 4 TB capacity, engineered for enterprise-level applications. It operates on a SAS 12 Gb/s interface, providing a high-speed connection suitable for data centers, servers, and storage arrays. The drive is designed for continuous, 24/7 operation, making it a component for systems that require constant data availability and integrity under demanding workloads. Its construction focuses on reliability for mid-range server and storage systems.

Performance is delivered through a 7200 RPM rotational speed and a 256 MB cache buffer, which facilitates efficient data handling and access. The drive achieves sustained read and write transfer rates of up to 243 MB/s. It features a Mean Time Between Failures (MTBF) rating of 2,000,000 hours and a workload rating of 550 TB per year, indicating its suitability for sustained use. This model also includes Self-Encrypting Drive (SED) technology that supports TCG Enterprise SSCs for data security.
