HP 697574-B21 1.2TB 10000 RPM SAS 6Gb/s 2.5" laptop hard drive

Enterprise SAS drive

The HP 697574-B21 is a 1.2TB 10000 RPM SAS 6Gb/s hard drive built for enterprise storage workloads. Its 2.5 inch small form factor fits dense server and storage arrays that demand high IOPS. The drive is new and ships in original or OEM packaging depending on supply. It targets IT teams running 24/7 databases, virtualisation hosts or transactional applications.

15mm bay integration

The unit measures 15mm in height, 76mm wide and 119mm long, so it slots into standard 2.5 inch 15mm drive bays and backplanes. A SAS 6Gb/s host bus adapter or RAID controller and a compatible backplane are required for connectivity. The single-connector SFF design frees the second bay position in dual-slot carriers for another drive. No tray is included, so the enclosure must supply its own mounting hardware.

Sustained 10K operation

At 10000 RPM the spindle maintains consistent throughput during extended read and write sequences typical of enterprise logs and OLTP databases. The SAS interface supports dual-port operation for multipath redundancy without performance loss during path failover. Mechanical latency stays predictable because the drive is engineered for continuous duty rather than burst-oriented desktop use. Heat output scales with sustained spindle speed, so the chassis must provide adequate airflow across the 15mm profile.
