MG04SCA500E Toshiba MG04 5TB SAS 64 MB 3.5" Server HDD

High-Density 3.5in SAS Enterprise HDD for Capacity Tiers with the MG04SCA500E

The MG04SCA500E is a 5TB 3.5in internal SAS enterprise HDD engineered for capacity-oriented server and storage platforms where predictable performance and sustained availability are required. In typical deployments, the MG04SCA500E sits behind modern CPU storage stacks and RAID controllers, providing an efficient capacity tier for file services, nearline datasets, and backup targets without consuming PCIe lanes needed for GPUs, NVMe, or high-bandwidth accelerators.

Using CMR recording and 7200 RPM mechanics, the MG04SCA500E supports stable write behavior under sequential and mixed workloads compared with shingled approaches. The 4Kn format with 512e emulation eases integration into heterogeneous operating systems and RAID/JBOD shelves, while Persistent Write Cache (PWC) helps protect in-flight data during power events. This architecture aligns with scale-out designs that prioritize slot density, serviceability, and controlled latency for large-volume datasets.

Why Choose the MG04SCA500E?

The MG04SCA500E is optimized for enterprise fleets that need a repeatable capacity building block with disciplined thermals and power behavior in dense enclosures. With a 24x7 duty rating and 1.4M hours MTBF, the MG04SCA500E supports long-lived arrays and predictable maintenance cycles, enabling scalable growth in SAS RAID or JBOD topologies while keeping cost and complexity aligned to capacity-tier objectives.

Toshiba designs the MG04 series with an enterprise reliability focus, combining controlled firmware behavior, power-loss-aware caching, and manufacturing discipline suitable for data center operational standards. The MG04SCA500E fits environments that demand consistent qualification, lifecycle continuity, and compatibility with established SAS infrastructure.

Key Applications:

• SAS JBOD and RAID expansion shelves
• Capacity tier storage in rack servers
• Nearline backup repositories
• Archive and large sequential workloads
• General-purpose file and service storage
