MG04SCA200E Toshiba MG04 2TB SAS 64 MB 3.5" Server HDD

High-Performance 3.5-inch Enterprise SAS Hard Drive for 24/7 Capacity Tiers with the MG04SCA200E

The MG04SCA200E is a 3.5-inch internal enterprise HDD engineered for SAS-based server and storage backplanes where consistent latency, predictable rebuild behavior, and continuous duty cycles are required. In dual-socket x86 compute nodes, storage servers, and expansion shelves, the MG04SCA200E integrates cleanly into SAS HBA or RAID controller architectures, supporting robust queue handling and deterministic block access for mixed sequential and random I/O patterns.

Designed around 7200 RPM CMR recording, the MG04SCA200E aligns with RAID arrays and general-purpose enterprise HDD pools by avoiding the write-amplification side effects that complicate parity updates on SMR media. Its 512e sector format supports modern OS and hypervisor stacks while remaining compatible with legacy alignment expectations, and the 64MB cache helps smooth burst writes typical of backup staging and log-heavy maintenance windows. The result is a balanced capacity building block for nearline tiers where PCIe NVMe is reserved for hot data and HDD pools deliver cost-efficient, serviceable growth.

Why Choose the MG04SCA200E?

The MG04SCA200E provides a stable density-to-performance profile for enterprises standardizing on 3.5-inch SAS bays, enabling predictable scaling across shelves and enclosures without redesigning the storage fabric. For IT teams managing uptime and rebuild windows, the MG04SCA200E supports operational consistency through 24/7 duty design, RAID-friendly CMR behavior, and straightforward deployment in single-port SAS infrastructures.

Toshiba’s enterprise storage engineering emphasizes sustained reliability, qualification discipline, and long-life component choices aligned with data centre service practices. With the MG04SCA200E, Toshiba targets continuous operation scenarios where firmware stability, consistent media behavior, and interoperability with common SAS controllers are key procurement requirements.

Key Applications:

• RAID arrays in rack servers
• Storage expansion shelves
• Backup repositories
• Nearline capacity tiers
