Capacity-Oriented 3.5-Inch SATA CMR Hard Drive for Legacy Storage Tiers with the ST31500541AS

The ST31500541AS is a 3.5-inch internal SATA hard drive engineered for capacity-first server and workstation storage where predictable throughput and cost-efficient bulk retention are prioritized over NVMe-class latency. In mixed-drive architectures, the ST31500541AS is commonly positioned behind compute nodes with modern CPU platforms and DRAM-centric memory hierarchies, providing a secondary tier that preserves primary flash resources for high-I/O datasets.

Designed for straightforward integration, the ST31500541AS attaches through a single SATA link, aligning with widespread backplane and HBA topologies and leaving PCIe lanes available for accelerators, high-speed NICs, or NVMe expansion. Its CMR magnetic recording supports consistent write behavior suitable for backup chains and cold-data repositories, while the 5900 RPM profile and 32MB cache balance sustained transfer patterns for low-to-moderate I/O services such as file shares, staging areas, and archival volumes.

Why Choose the ST31500541AS?

The ST31500541AS delivers a pragmatic density-to-deployment fit for enterprises maintaining SATA-based platforms, needing stable capacity scaling without redesigning storage enclosures or changing operational processes. The ST31500541AS is well suited for reliable, repeatable provisioning in fleets where serviceability, standard drive bays, and predictable behavior under sequential workloads are more valuable than peak IOPS.

Seagate designs storage to integrate cleanly into enterprise maintenance cycles, emphasizing consistent firmware behavior, broad platform interoperability, and manufacturing controls aligned with modern data centre qualification practices.

Key Applications:

• Backup repositories
• Cold data retention
• Low-I/O secondary storage tiers
• Legacy SATA server capacity expansion
