HDD Toshiba 4 TB 3.5 inch SAS MG10SDA400E

The Toshiba MG10SDA400E is a 4 TB 3.5" SAS enterprise hard drive engineered for sustained, 24/7 operation in server and storage arrays. With a rotational speed of 7,200 RPM and a 512 MB buffer, this drive is designed to deliver consistent throughput and low access latency for demanding workloads. The dual-port SAS interface and 3.5" form factor make it suitable for rack-mounted systems, storage enclosures and industrial servers where reliability, high capacity and predictable performance are required.

Advantages

This HDD provides a high formatted capacity of 4 TB combined with a 7,200 RPM spindle speed and a large onboard cache to improve read/write responsiveness under mixed workloads. It is built for continuous operation with a workload rating aligned to enterprise demands and incorporates rotational vibration (RV) sensors to reduce multi-bay vibration effects. Toshiba’s persistent write cache and advanced platter and cache management technologies help protect data integrity during unexpected power interruptions and optimize performance in real-time environments.

Suitable for

• Enterprise storage arrays and clustered storage systems
• Industrial and rack-mounted servers
• Cloud-scale infrastructure and data center applications
• Backup appliances and nearline archival storage
• Read/write intensive business applications and virtualization hosts
