MG04SCA500A Toshiba MG Enterprise Capacity MG04SCA 5TB SATA 64 MB 3.5" Server HDD

High-Capacity 3.5in SATA Enterprise HDD for 24x7 Bulk Storage with the MG04SCA500A

The MG04SCA500A is a 5TB 3.5in internal enterprise HDD engineered for predictable capacity scaling in SATA server and storage platforms where cost-efficient bulk tiers are required alongside continuous 24x7 duty operation. Designed for classic CPU-based storage nodes and RAID controllers, the MG04SCA500A fits architectures prioritising sequential throughput consistency, controlled latency under queue, and operational stability across dense drive populations.

Using CMR recording and a 4Kn sector format, the MG04SCA500A aligns with modern filesystems and storage stacks that are optimised for 4KB-native writes, reducing read-modify-write penalties and improving rebuild behaviour in large RAID arrays. The 64MB cache supports command and data buffering for mixed read/write patterns typical of backup windows, file services, and application repositories. With a single-port SATA interface, the MG04SCA500A integrates cleanly into standard 3.5in bays, backplanes, and JBOD shelves where expansion is driven by drive count rather than PCIe lane availability.

Why Choose the MG04SCA500A?

The MG04SCA500A provides an enterprise-centric balance of capacity density, serviceability, and reliability for organisations building large SATA pools for OS repositories, bulk capacity tiers, and archive targets. By combining CMR with 4Kn, the MG04SCA500A supports scalable RAID deployments with predictable performance characteristics and a pragmatic path to higher usable capacity per rack unit without re-architecting the host platform.

Toshiba designs the MG series with a focus on sustained operation, qualification for data centre environments, and compatibility with established enterprise storage standards, enabling consistent lifecycle management across multi-vendor server infrastructures.

Key Applications:

• Server boot and OS storage tiers
• RAID arrays for bulk capacity
• Backup targets
• Archive repositories
• General-purpose file and application storage
