MG04SCA200A Toshiba MG04 2TB SAS 64 MB 3.5" Server HDD

High-Performance 3.5-inch Enterprise SAS HDD featuring 4Kn CMR reliability with the MG04SCA200A

The MG04SCA200A is a 3.5-inch enterprise HDD designed for SAS rack servers and storage arrays where predictable latency, sustained throughput, and 24/7 duty cycles are required. As a 7.2K RPM, CMR drive with 4Kn native sectors, it aligns with modern storage stacks that prioritize consistent write behavior and data integrity across mixed read/write enterprise workloads.

In server architectures, the MG04SCA200A integrates cleanly behind SAS HBAs or RAID controllers, supporting scalable backplanes and JBOD enclosures for capacity tiers. The 4Kn format helps reduce sector translation overhead in environments that are standardized on 4KB I/O paths, while CMR recording supports rebuild operations and long sequential streams common in backup repositories. With a 64MB cache and single-port SAS connectivity, the MG04SCA200A is suited for cost-controlled, high-availability designs where drive-level behavior must remain stable under sustained queue depth.

Why Choose the MG04SCA200A?

The MG04SCA200A provides a balanced density-to-performance profile for enterprise capacity tiers, delivering operational consistency in always-on deployments and straightforward scaling in multi-bay server and JBOD configurations. It is a practical choice when platform architects need deterministic HDD behavior for RAID groups, predictable rebuild characteristics, and dependable service life in continuous-operation environments.

Toshiba designs the MG series with an engineering focus on controlled thermals, mechanical stability, and firmware behavior aligned to data centre duty cycles. The MG04SCA200A reflects this approach by supporting enterprise qualification processes and compatibility expectations for SAS storage ecosystems.

Key Applications:

• Rack server HDD capacity tier
• SAS JBOD and storage arrays
• Backup and archive repositories
• General-purpose enterprise storage
• 24/7 continuous operation environments
