The HP 652564-B21 is a 300 GB enterprise-class SAS hard drive designed for use in HP/HPE ProLiant servers and storage arrays. It features a 6 Gb/s SAS interface and 10,000 RPM rotational speed to deliver strong performance for mission-critical workloads such as virtualization, database access, and RAID storage. Its 2.5-inch Small Form Factor (SFF) and hot-swappable design make it ideal for dense rack/tower server environments that require reliability and uptime.
This drive often ships with an HP Smart Carrier (SC) for easy serviceability and status indication on server front panels.
300 GB Capacity: Enterprise-oriented storage suitable for system volumes, RAID members, and high-IO workloads.
10,000 RPM Spindle: Faster rotational speed ensures lower latency and better response compared with standard 7.2K drives.
6 Gb/s SAS Interface: High reliability and throughput ideal for server storage controllers.
SAS Dual Port Support: Provides redundant paths for improved data availability (supported by most enterprise HP SAS configurations).
Hot-Swappable: Can be replaced while the server is running (with compatible hardware).
Built for 24×7 operation in critical server and data-center environments.
Smart Carrier: Easy drive insertion/removal with LED indicators (model dependent).
Tested Compatibility: Works across a wide range of HP ProLiant server generations.
