Capacity and interface

This HP 652589-B21 drive provides 900 GB of storage on a 2.5 inch SAS 6Gb/s interface spinning at 10000 RPM. It is built for enterprise storage arrays and servers that require dual-port SAS connectivity and high transaction throughput. The 15.6 mm z-height fits standard small form factor hot-plug bays.

Suited for high-IO enterprise workloads

The drive targets environments running databases, virtualization hosts or other high transaction applications that benefit from 10000 RPM spindle speed and SAS reliability. It is not intended for desktop PCs lacking a SAS controller or backplane, nor for users who need larger capacity per drive or the lower power draw of solid-state storage.

10000 RPM spindle speed

The 10000 RPM rotational speed is the key determinant for random I/O performance and latency in transaction-heavy workloads. Verify that your chassis, controller and cooling design support 2.5 inch 15.6 mm enterprise SAS drives before purchase.
