Seagate Constellation.2 500GB 2.5" 7200RPM SATA 6 Gb/s Internal HDD

The Seagate ST9500620NS is a 2.5 inch internal hard drive that offers 500GB of storage through a SATA 6 Gb/s interface. Built on the Constellation.2 platform, it gives you enterprise reliability in a bay size that fits blade servers, compact rack systems, and high-density storage arrays.

With a spindle speed of 7200 RPM and a 64MB cache, this drive moves data quickly enough for transactional databases, virtualization hosts, and streaming workloads. The consistent throughput helps applications stay responsive even when multiple users are accessing the same volume around the clock.

Reliability is at the center of the design. The drive is rated for a mean time between failures of 1.4 million hours and is validated for continuous 24×7 operation. Firmware enhancements and a construction that resists vibration maintain steady performance when dozens of drives share the same chassis.

PowerChoice technology trims power usage during idle periods to less than 6.4 watts, which lowers heat generation and eases the load on data-center cooling systems. This efficiency is especially valuable in dense deployments where every watt saved helps extend the life of supporting hardware.

System integrators, IT managers, and anyone upgrading mission-critical servers will find the ST9500620NS a natural fit. Its standard SATA interface simplifies replacement planning, while the 15mm height slides directly into common enterprise drive trays without adapters or cabling changes.

Highlights:

• 500GB capacity in a 2.5 inch form factor with 15mm height
• 7200 RPM spindle speed and SATA 6 Gb/s interface for fast transfers
• 64MB cache supports steady throughput during heavy workloads
• Rated for 1.4 million hours MTBF and validated for 24×7 duty cycles
• Firmware tuned for vibration resistance in multi-drive chassis
• PowerChoice technology lowers idle power draw to under 6.4 watts
