MG04SCA50EA Toshiba MG04 5TB SAS 128 MB 3.5" Server HDD

High-Performance 3.5-inch Enterprise SAS Nearline HDD featuring 4Kn CMR capacity-tier storage with the MG04SCA50EA

MG04SCA50EA is a 3.5-inch 7,200 RPM enterprise SAS nearline HDD designed for capacity tiers in server and storage platforms where predictable latency, controlled rebuild behavior, and 24x7 duty cycles are mandatory. In modern dual-socket CPU environments and virtualized clusters, the MG04SCA50EA complements DRAM-heavy cache layers by providing economical bulk capacity behind RAID controllers or HBA-based JBOD, while keeping sustained performance consistent through CMR recording.

Architecturally, MG04SCA50EA aligns with SAS backplanes and expander topologies commonly used in dense storage shelves, enabling straightforward integration into PCIe-attached storage stacks without consuming valuable NVMe lanes reserved for hot data. Its 4Kn native sector format supports contemporary file systems and object/archive designs that standardize on 4KB I/O, while persistent write cache behavior helps stabilize write acknowledgement paths under controller-managed caching. The MG04SCA50EA is therefore suited to backup repositories, general-purpose volumes, and retention pools where capacity, reliability, and operational discipline outweigh ultra-low latency.

Why Choose the MG04SCA50EA?

MG04SCA50EA provides a practical density-to-performance balance for scale-out capacity growth, with enterprise reliability characteristics such as 24x7 rating and 1.4M hours MTBF. For IT teams standardizing on SAS RAID/JBOD architectures, MG04SCA50EA simplifies fleet planning with consistent 4Kn behavior, controllable power profile, and secure lifecycle handling suitable for multi-tenant or regulated environments.

Toshiba designs MG-series nearline drives with a focus on predictable operation in data center duty cycles, emphasizing validated firmware behavior, interoperability with SAS storage ecosystems, and features that support secure decommissioning and operational continuity under sustained workloads.

Key Applications:

• SAS JBOD capacity expansion
• RAID arrays for nearline storage
• Backup and recovery repositories
• File services and general-purpose volumes
• Archive and retention storage
