MG04ACA500E Toshiba MG04 5TB SATA 128 MB 3.5" Server HDD

High-Capacity 3.5in SATA Enterprise HDD for 24x7 Scale-Out Storage with the MG04ACA500E

The MG04ACA500E is a 3.5in internal enterprise HDD engineered for capacity-centric storage tiers where predictable latency and continuous operation matter more than ultra-low access time. In server and JBOD designs, it complements modern CPU platforms by offloading bulk datasets from expensive compute-attached flash, enabling higher memory efficiency and cleaner cache hierarchies for backup, archive, and general-purpose file services.

Designed for SATA backplanes and standard RAID/HBA topologies, the MG04ACA500E uses CMR recording at 7200RPM to maintain consistent write behavior under sustained ingest compared with SMR approaches. Its 512e sector format with 4Kn emulation supports broad OS and controller compatibility, while the 128MB cache helps smooth mixed sequential workloads typical in repository and object-like access patterns. Power characteristics support dense chassis planning across multi-drive enclosures where thermal and PSU budgets are tightly managed.

Why Choose the MG04ACA500E?

The MG04ACA500E provides a practical density-to-cost profile for scale-out nodes and shared storage shelves, delivering dependable performance under 24x7 duty cycles. With an MTBF rating of 1.4M hours, the MG04ACA500E aligns to enterprise reliability expectations for large drive counts, helping architects standardize capacity pools and scale incrementally without changing interface infrastructure.

Toshiba designs the MG series with a focus on controlled manufacturing, stable firmware behavior, and long-life components suited for continuous operation in rack servers and JBOD environments. The MG04ACA500E fits modern data centre requirements by supporting consistent SATA interoperability, serviceable deployment in hot-swap bays, and operational predictability across heterogeneous storage stacks.

Key Applications:

• Scale-out storage nodes
• JBOD shelves
• Backup repositories
• Archive and cold tiers
• Entry enterprise and SMB servers
