ST300MM0048 Seagate Exos 0.3TB SAS 128 MB 2.5" HDD

High-Performance 2.5in SAS Enterprise HDD for OS and Tiered Storage with the ST300MM0048

The ST300MM0048 is a 2.5in 10K RPM SAS enterprise hard drive engineered for predictable latency and consistent IOPS in server and storage backplanes, making it well suited for OS volumes, hot spare pools, and performance tiers within larger RAID sets. With a 512n sector format and CMR recording, the ST300MM0048 integrates cleanly into enterprise controller ecosystems where deterministic write behavior and rebuild stability are critical.

In modern x86 server platforms, the ST300MM0048 complements CPU and memory resources by providing reliable block storage for boot, logging, and service partitions while NVMe or SSD tiers handle cache and acceleration. SAS connectivity supports multi-drive expansion via HBAs and RAID controllers, enabling scalable PCIe-attached storage architectures in rack servers and SAN/JBOD enclosures. PowerChoice power management helps optimize thermal and power envelopes across dense 2.5in SFF bays during 24x7 operation.

Why Choose the ST300MM0048?

The ST300MM0048 delivers a balanced density-to-performance profile for enterprises that need compact SAS media with predictable behavior under mixed workloads and sustained duty cycles. With 2.0M hours MTBF and Protection Information (PI) support, the ST300MM0048 aligns with integrity-focused deployments where end-to-end data protection, serviceability, and fleet consistency drive procurement and lifecycle planning.

Supermicro storage engineering emphasizes platform compatibility, validated component interoperability, and operational reliability in standard data centre environments. Designed for continuous service in server bays and expansion shelves, the ST300MM0048 fits into Supermicro-aligned architectures where airflow, backplane signaling, and controller features are tuned for enterprise uptime expectations.

Key Applications:

• Server boot and OS media in 2.5in SAS SFF bays
• SAS RAID arrays for tiered enterprise storage
• SAN JBOD expansion shelves
• Log, telemetry, and infrastructure services volumes
