MG04ACA500A Toshiba MG04 5TB SATA 128 MB 3.5" Server HDD

High-Capacity 3.5in Enterprise SATA HDD featuring 4Kn CMR integrity with the MG04ACA500A

The MG04ACA500A is a 3.5in internal enterprise HDD engineered for high-capacity SATA tiers where predictable latency, consistent write behavior, and service continuity matter more than peak IOPS. In server platforms based on current x86 CPU generations, the drive complements DRAM-centric caching and RAID controller offload by providing a stable bulk-storage layer with CMR recording and 4Kn sector formatting, reducing translation overhead in modern filesystems aligned to 4KB blocks.

In PCIe-based storage architectures, the MG04ACA500A typically sits behind SAS/SATA HBAs or RAID adapters, freeing PCIe lanes for NVMe acceleration while sustaining economical capacity scaling for backup targets and nearline datasets. Its 7200RPM design and cache architecture support sustained sequential workloads common in retention tiers, while the SATA interface keeps integration straightforward across dense rack servers, JBOD shelves, and edge appliances that prioritize serviceability and standardized cabling.

Why Choose the MG04ACA500A?

The MG04ACA500A delivers a practical density-to-performance balance for enterprises building large SATA pools, where capacity growth must not compromise operational predictability. With 24x7 duty cycle design and enterprise reliability targets, the MG04ACA500A is well suited for RAID groups and scale-out storage nodes that require repeatable rebuild behavior and disciplined write characteristics under continuous load.

Toshiba designs the MG series around datacenter reliability fundamentals: controlled vibration tolerance expectations for multi-drive environments, consistent manufacturing validation, and an engineering focus on long-life operation aligned with modern data centre maintenance cycles and standardized monitoring practices.

Key Applications:

• RAID arrays and JBOD capacity tiers
• Backup repositories and archival targets
• Always-on file services
• Video retention at edge and branch sites
• Log and telemetry data staging
