MG03SCA300 Toshiba MG03SCA 3TB SAS 64 MB 3.5" Backup HDD

High-Performance 3.5-inch Enterprise SAS HDD for 24/7 Drive Bays with the MG03SCA300

The MG03SCA300 is a 3.5-inch internal enterprise HDD engineered for SAS-based storage shelves and server backplanes where predictable latency and continuous duty cycles are mandatory. As a 7,200 RPM CMR drive with 512e sector format, the MG03SCA300 aligns well with mixed OS and hypervisor stacks while maintaining consistent write behavior for RAID groups and rebuild operations.

Designed for scale-out infrastructure, the MG03SCA300 integrates cleanly into SAS topologies using a single-port interface, supporting dense arrays where controller-managed caching and tiering handle performance aggregation. The 64MB cache and CMR recording model help stabilize sustained throughput for sequential backup streams and general-purpose enterprise HDD tiers, while 3TB capacity targets balanced cost-per-bay planning in cloud and on-prem storage pools. For systems engineers, the MG03SCA300 is a pragmatic choice for environments that prioritize deterministic behavior, compatibility, and service life over burst-heavy profiles.

Why Choose the MG03SCA300?

The MG03SCA300 delivers an enterprise-appropriate density-to-reliability profile for always-on deployments, pairing 3.5-inch capacity with operational characteristics suited to 24/7 data centre drive bays. With a 1.2M hours MTBF target, the MG03SCA300 supports scalable RAID and backup architectures where predictable availability, controlled failure domains, and consistent media behavior simplify fleet operations and lifecycle planning.

Toshiba designs enterprise HDD platforms with a focus on sustained operation, qualification discipline, and electrical/thermal tolerance aligned to modern rack-scale storage standards. The MG03SCA300 reflects this approach through power characteristics suited to populated chassis and an operating temperature range appropriate for controlled airflow in dense enclosures.
