ST300MX0022 Seagate Enterprise Performance 15K 0.3TB SAS 128 MB 2.5" Server HDD

High-Performance 2.5in SAS Enterprise HDD delivering low-latency transactional I/O with the ST300MX0022

The ST300MX0022 is a 2.5in, 15K RPM SAS enterprise HDD engineered for high-IOPS, low-latency profiles in dense server and storage nodes. Designed for SAS backplanes and dual-path enterprise connectivity, it supports consistent behavior under sustained queue depth, making it well aligned to OLTP databases, log-heavy services, and virtualised boot tiers where predictable response time matters more than raw capacity.

Within modern x86 server platforms, the ST300MX0022 integrates cleanly into RAID controllers and HBA-based architectures, allowing predictable scaling across multi-bay chassis. Its CMR media and 4Kn with 512e emulation provide sector-format flexibility for mixed OS and hypervisor deployments, while the 128MB cache supports burst absorption for metadata and journal activity. For security-focused environments, hardware-based encryption via SED with TCG Enterprise enables at-rest protection without consuming CPU cycles, fitting operational models that require rapid drive replacement and secure decommissioning.

Why Choose the ST300MX0022?

The ST300MX0022 provides an efficient density-to-performance ratio for hot data tiers where SAS reliability, deterministic latency, and serviceability are operational requirements. Its 24x7 duty-cycle design and 2.0M-hour MTBF profile support scale-out deployments, while the compact 2.5in footprint improves airflow and bay utilization in compute sleds and storage shelves.

Seagate designs enterprise drives around consistent firmware behavior, validated interoperability, and lifecycle discipline for data centre operations. The platform focus prioritizes sustained performance, secure handling, and compatibility with standard SAS management and monitoring practices in modern racks.

Key Applications:

• High-IOPS transactional databases and OLTP
• Virtualised server boot volumes
• Hypervisor and application log storage
• Tiered storage hot data in SAS backplanes
