MG04SCA40EE Toshiba 4TB SAS 128 MB 3.5" Server HDD

High-Performance 3.5in Enterprise SAS HDD featuring CMR reliability with the MG04SCA40EE

The MG04SCA40EE is a 3.5in internal enterprise SAS hard drive designed for server and JBOD storage tiers where predictable latency and consistent write behavior matter more than peak IOPS. In dual-controller arrays or single-server backplanes, the MG04SCA40EE aligns with standard SAS HBA and RAID architectures to deliver stable performance for mixed read/write duty cycles and 24x7 operation.

Built around 7,200 RPM media and CMR recording, the MG04SCA40EE maintains steady write throughput under RAID rebuilds, log-intensive workloads, and multi-stream ingestion without the variability associated with shingled layouts. Advanced Format 4K sectors with 512e support integrate cleanly with modern OS and hypervisor stacks, while onboard cache helps smooth bursts and queue depth variation across shared storage fabrics. Data-protection functions such as Persistent Write Cache and power-loss safeguards are engineered to reduce exposure during unexpected outages, supporting disciplined storage integrity practices.

Why Choose the MG04SCA40EE?

The MG04SCA40EE provides an efficient capacity-to-bay ratio for enterprise platforms that require SAS manageability, consistent CMR behavior, and predictable service characteristics at scale. It fits cleanly into expansion shelves and RAID groups, supporting straightforward growth paths and repeatable deployment patterns across standard 3.5in SAS infrastructures.

Toshiba engineers the MG-series with an emphasis on continuous-duty reliability, controlled firmware behavior, and compatibility with common data centre qualification processes. The MG04SCA40EE supports modern operational requirements through durable mechanics, enterprise error-handling expectations, and features aimed at maintaining data integrity throughout the drive lifecycle.

Key Applications:

• RAID arrays in rack servers
• JBOD capacity expansion tiers
• Virtualization datastores
• Backup and archive repositories
• General-purpose mixed read/write workloads
