Seagate Constellation 500GB 2.5" 7200RPM SATA 3Gb/s Internal HDD

The Seagate ST9500530NS is a 2.5-inch hard drive from the Constellation family that gives servers and storage arrays 500GB of reliable, enterprise-class capacity. Designed for demanding, always-on workloads, it fits neatly into dense chassis while delivering rotational speed that keeps data moving quickly.

Its 7200 RPM mechanism works with a SATA 3Gb/s interface and a 32MB cache to provide consistent throughput for database activity, virtualized environments, and high-volume file sharing. Whether the system is reading large sequential files or serving many small random requests, the drive sustains performance that helps keep applications responsive.

Reliability sits at the core of this model. A 1.2 million hour MTBF rating, advanced vibration resistance, and firmware tuned for continuous 24×7 duty give administrators confidence when deploying it in multi-drive enclosures. PowerChoice technology further trims energy use by lowering idle consumption to less than 4 watts, a benefit that reduces heat and operating costs in space-constrained racks.

Installers who need high density storage for blade servers, compact NAS units, or edge appliances will appreciate the 15mm height that allows tight stacking without sacrificing robust construction. From branch offices to data centers, the drive offers a straightforward way to expand capacity while maintaining the performance and durability expected in enterprise settings.
