High-Performance 3.5in Enterprise SAS HDD featuring CMR Nearline Capacity with the MG03SCA400
The MG03SCA400 is a 3.5in enterprise SAS hard drive engineered for predictable, continuous-duty storage tiers in modern data centres. Designed for 24/7 operation, the MG03SCA400 targets bulk storage and nearline roles where capacity efficiency and consistent latency matter more than peak IOPS, while maintaining the operational discipline required for server and JBOD deployments.
In storage architectures built around SAS backplanes and expander topologies, the MG03SCA400 integrates cleanly into dual-ported paths and controller-managed RAID arrays, supporting scale-out shelves without changing host platforms. Its CMR recording helps sustain steady write behaviour under rebuild and background maintenance activity, and its 4Kn format with 512e emulation supports both modern sector-aligned filesystems and mixed-legacy integration. With 7,200 RPM mechanics and cache buffering, the MG03SCA400 is well suited for balanced throughput in sequential and mixed workloads common to tiered repositories, backup staging, and archival pools.
Why Choose the MG03SCA400?
The MG03SCA400 provides an enterprise-focused density-to-throughput profile for nearline tiers, combining SAS interoperability with the consistency benefits of CMR for RAID integrity and rebuild stability. The MG03SCA400 is an appropriate choice when you need predictable behaviour in multi-drive arrays, controlled power characteristics for always-on environments, and straightforward scaling across servers and external enclosures.
Toshiba designs the MG series with a reliability-first engineering philosophy, emphasizing controlled thermals, qualification discipline, and compatibility with data centre storage standards. With the MG03SCA400, Toshiba aligns mechanical design, firmware behaviour, and continuous-duty ratings to support long-lived deployments in managed infrastructure.
Key Applications:
- Data centre bulk storage
- Nearline tiering
- RAID arrays in rack servers
- JBOD expansion enclosures
- Backup and archival repositories
