MG10ADA400N Toshiba MG Series 4TB SATA 512 MB 3.5" Server HDD

High-Performance 3.5-inch Enterprise SATA HDD featuring CMR nearline capacity with the MG10ADA400N

The MG10ADA400N is a 3.5-inch internal enterprise HDD designed for capacity-focused server and NAS architectures where predictable behavior under mixed IO matters more than peak IOPS. Integrated into standard x86 rack platforms and storage nodes, the MG10ADA400N supports a SATA storage plane that complements CPU and memory resources by sustaining steady sequential throughput for backup, media repositories, and bulk datasets.

Using CMR recording and a 7200RPM design, the MG10ADA400N avoids the performance volatility associated with shingled media in rebuild and scrub operations, making it suitable for RAID groups and nearline tiers. The 512n sector format simplifies alignment and legacy OS compatibility in heterogeneous fleets, while the 512MB cache and Persistent Write Cache help maintain data integrity during transient power events and reduce exposure to incomplete writes. Its power profile supports dense multi-bay chassis planning where thermal and PSU headroom are engineered constraints.

Why Choose the MG10ADA400N?

The MG10ADA400N delivers an enterprise reliability profile for 24x7 operation and scales cleanly from small NAS enclosures to large RAID shelves, enabling consistent capacity expansion without changing the storage protocol. For IT teams standardizing on SATA backplanes, the MG10ADA400N provides a pragmatic density-to-cost balance with CMR behavior that is operationally predictable during rebuild windows and maintenance cycles.

Toshiba designs the MG-series around disciplined mechanical engineering, firmware validation, and sustained duty-cycle expectations, aligning with modern data center requirements for reliability, serviceability, and long-term platform stability in mixed-vendor storage stacks.

Key Applications:

• General-purpose server bulk storage
• NAS capacity expansion
• RAID arrays and rebuild-sensitive tiers
• Nearline storage pools
• Backup and archival repositories
