Toshiba MG09SCA 18TB SAS HDD – High-Speed, High-Reliability Storage for Enterprise Workloads

The Toshiba MG09SCA18TE from the MG9SCA Series is a robust and high-performance 18TB SAS enterprise HDD, purpose-built for heavy-duty, always-on environments. Designed with data centers, hyperscale infrastructure, and large enterprise storage solutions in mind, this 3.5-inch internal hard drive combines massive capacity with outstanding speed and reliability.

Equipped with a SAS 12Gbit/s interface, 7200 RPM rotational speed, and a large 512MB buffer cache, this drive delivers up to 268 MiB/s sustained transfer speed. It’s optimized to support continuous workloads with consistent throughput, ideal for file servers, enterprise RAID arrays, and cloud-based applications that require secure and scalable storage.

Built for Enterprise Environments

The MG09SCA Series is engineered for high-end IT infrastructure that demands around-the-clock performance. With a workload rating of 550TB/year, the Toshiba MG09SCA18TE easily handles intensive read/write operations that go beyond the capacity of conventional hard drives.

Its SAS 12Gb/s interface provides faster, more secure, and more stable data throughput compared to SATA. This makes it the preferred choice for mission-critical applications, including virtualization, analytics, and cloud storage.

Energy-Efficient Storage Without Sacrificing Power

Despite its high-performance output, the drive maintains energy efficiency with only 4.49W idle power consumption. That’s ideal for data centers and enterprise storage solutions aiming to reduce operating costs and improve thermal efficiency.

Its balance between capacity, power use, and sustained performance makes it suitable for both scale-up and scale-out storage deployments.

Enterprise-Grade Durability and Reliability

Toshiba designed the MG09SCA18TE with vibration sensors, enhanced error recovery, and advanced firmware tuning to deliver long-term reliability. It’s built for 24/7 operation, even in multi-drive systems and high-density server racks.

This 18TB SAS drive also supports 512e (Advanced Format) to enhance data integrity and compatibility across modern enterprise software platforms.
