MG10SDA400N Toshiba MG Enterprise Capacity 4TB SAS 512 MB 3.5" Server HDD

High-Performance 3.5in Enterprise SAS HDD for Capacity-Centric Storage Tiers with the MG10SDA400N

The MG10SDA400N is a 3.5in enterprise SAS HDD engineered for 24/7 datacenter duty where predictable throughput, serviceability, and cost-efficient capacity are required. As a 7200RPM CMR drive, the MG10SDA400N supports consistent write behavior under sustained load, making it a practical building block for RAID groups, shared storage shelves, and capacity-oriented pools in rack servers and external JBOD architectures.

In modern CPU platforms with high core counts and dense memory footprints, storage tiers must prevent queue bottlenecks while remaining power-aware. The MG10SDA400N integrates a 512MB cache with Persistent Write Cache (PWC) support to help protect in-flight data during transient power events, and its 512B native (512n) formatting aligns with legacy and enterprise OS expectations for predictable block handling. Deployed behind SAS HBAs or in storage backplanes, the MG10SDA400N scales cleanly across multi-drive enclosures, complementing PCIe-based NVMe tiers by absorbing bulk datasets, sequential backups, and mixed read/write repositories without over-consuming premium flash capacity.

Why Choose the MG10SDA400N?

The MG10SDA400N delivers an enterprise reliability profile and a strong density-to-performance balance for capacity tiers, with a 2.25M hours MTTF target and operational characteristics suited to sustained arrays. For architects standardizing on SAS for dual-path connectivity and consistent fleet management, the MG10SDA400N supports straightforward scale-out across servers and storage nodes while maintaining predictable behavior under RAID rebuild and backup windows.

Toshiba designs the MG-series around disciplined manufacturing control, endurance-focused mechanics, and firmware tuned for datacenter interoperability, aligning with modern operational standards for continuous duty cycles, controlled power draw, and long-term platform consistency.

Key Applications:

• SAS HDD storage tiers in rack servers
• RAID arrays and shared JBOD shelves
• Backup repositories and retention pools
• Archival and compliance storage on HDD
• General-purpose mixed read/write datasets
