MG04SCA50EE Toshiba MG04 5TB SAS 128 MB 3.5" Server HDD

High-Performance 3.5-inch Enterprise SAS HDD for nearline capacity tiers with the MG04SCA50EE

The MG04SCA50EE is a 3.5-inch internal enterprise HDD designed for SAS server and storage platforms where sustained throughput, predictable latency, and controlled rebuild behavior are required in capacity-oriented tiers. Integrated into dual-ported SAS backplanes, the MG04SCA50EE supports consistent 24/7 duty cycles and operational profiles common to RAID pools in storage arrays and dense rack servers.

Architecturally, the MG04SCA50EE aligns with capacity-first designs that prioritize dependable sequential performance over PCIe/NVMe expansion, making it a practical complement to CPU-centric compute nodes that need economical bulk storage for datasets, backups, and archives. Its CMR recording model and 4Kn (512e emulation) formatting help maintain stable write characteristics and compatibility across modern controllers, while onboard cache contributes to smoother burst handling under mixed read/write patterns.

Why Choose the MG04SCA50EE?

The MG04SCA50EE delivers a balanced density-to-performance profile for enterprise nearline tiers, enabling scalable RAID HDD pools without compromising operational predictability. With continuous-operation rating and enterprise reliability characteristics, the MG04SCA50EE fits deployments where service continuity, controlled maintenance windows, and long lifecycle platform standardization are key.

Toshiba designs the MG series around disciplined mechanical and firmware engineering, targeting consistent behavior under sustained load and alignment with data centre requirements for reliability, controllability, and long-term supply stability. The MG04SCA50EE reflects this approach through enterprise-focused protection mechanisms and format options suited to modern SAS ecosystems.

Key Applications:

• Nearline capacity tiers in storage arrays
• RAID HDD pools and SAS JBOD shelves
