MD04ACA400 Toshiba MD04 Client 4TB SATA 128 MB 3.5" Consumer HDD

Enterprise 3.5in SATA Capacity HDD featuring CMR recording consistency with the MD04ACA400

The MD04ACA400 is a 3.5in internal SATA hard disk designed for capacity-oriented tiers where predictable write behavior and cost-efficient bulk storage matter more than low-latency IOPS. In mixed desktop and SOHO server environments, the MD04ACA400 supports stable sequential throughput through 7200RPM mechanics and CMR recording, reducing performance variability during sustained writes compared with shingled approaches.

Architecturally, the MD04ACA400 integrates cleanly into standard SATA backplanes and controller ports, enabling straightforward scaling in DAS/NAS enclosures and entry rack systems without consuming PCIe lanes for storage expansion. With 512e sector emulation, the MD04ACA400 aligns with modern OS and RAID stack expectations while maintaining broad compatibility for legacy tooling and imaging workflows. A 128MB cache helps smooth burst traffic for file services, backup staging, and media repositories where queue depth is moderate and throughput consistency is the primary target.

Why Choose the MD04ACA400?

The MD04ACA400 delivers a practical density-to-performance balance for secondary tiers, providing repeatable CMR write behavior, predictable rebuild characteristics in SATA arrays, and a power profile suited to always-on SOHO deployments. Selecting the MD04ACA400 is a rational approach when scaling bulk capacity across multiple bays while keeping integration simple and service procedures familiar to operations teams.

Toshiba designs its MD04-series drives with disciplined mechanical engineering and qualification practices aimed at dependable long-run operation in standard chassis airflow and vibration conditions, aligning with common data centre and edge storage standards for SATA-based capacity pools.

Key Applications:

• Desktop bulk storage
• SOHO NAS/DAS storage pools
• Backup staging and rotation
• Archive and cold data repositories
• Media libraries and file shares
