HP 652564-B21 300GB SAS 10K 2.5IN SC ENT HDD

The HP 652564-B21 is a 300GB SAS hard drive engineered for enterprise server environments where performance, reliability, and serviceability are essential. Spinning at 10,000 RPM and connected via a 6Gb/s SAS interface, this drive delivers the throughput and low-latency response times needed for database operations, virtualization hosts, email servers, and other transaction-heavy workloads. The 2.5-inch Small Form Factor design allows for high-density storage configurations in HP ProLiant server chassis, letting administrators pack more drives into less rack space.

One of the key advantages of this drive is its hot-swap capability using the HP SmartDrive Carrier, which enables technicians to replace failed or aging drives without shutting down the server — a critical feature for environments that demand high uptime. As a genuine HP part (PN: 652564-B21), it is validated for seamless integration with HP server platforms, supported by HP firmware and management tools. While the 300GB capacity is modest by today's standards, it remains a practical choice for boot drives, OS partitions, or workloads where speed matters more than raw capacity, and where the total cost of ownership favors proven SAS spinning media over premium enterprise SSDs.
