ST1200MM0009 Seagate Exos 10E2400 1.2TB SAS 128 MB 2.5" Server HDD

High-Density 2.5in SAS Enterprise HDD featuring 10K RPM performance with the ST1200MM0009

The ST1200MM0009 is a 2.5in internal SAS enterprise hard drive designed for servers and storage systems that require consistent low-latency HDD behavior in dense chassis. In mixed CPU virtualization and general-purpose storage tiers, ST1200MM0009 provides predictable rotational performance for boot/media volumes, hot data sets, and transactional logging where SSD-only architectures are not required.

Built for SAS backplanes and RAID controllers, ST1200MM0009 aligns with enterprise PCIe-based server platforms by offloading bulk media to a proven 10K RPM tier while preserving PCIe lanes for NVMe and accelerator expansion. The 512n Advanced Format simplifies legacy OS compatibility and reduces translation overhead in tightly controlled boot images. With 128MB cache and a 1.2TB capacity point, ST1200MM0009 supports scale-out storage nodes that balance capacity per RU with consistent service times across large drive counts.

Why Choose the ST1200MM0009?

The ST1200MM0009 delivers a practical density-to-performance ratio for compact arrays where 2.5in slots are the limiting factor and operational consistency matters more than peak throughput. ST1200MM0009 is engineered for enterprise reliability profiles and predictable RAID rebuild behavior, with Protection Information support to improve end-to-end data integrity and Instant Secure Erase for controlled decommissioning and compliance-aligned lifecycle operations.

Seagate designs its enterprise HDD platforms with firmware tuning for multi-drive environments, power management features such as PowerChoice for data centre efficiency targets, and qualification against modern server storage standards. With a 2.0M hours MTBF class and stable operating characteristics, Seagate focuses on long service life in always-on infrastructure.

Key Applications:

• Server boot and media volumes
• General-purpose enterprise storage tiers
• Transactional logging and low-latency HDD workloads
• RAID arrays requiring predictable rebuild behavior
