Seagate ST373455SSCheetah 73GB SAS15K

Seagate Cheetah ST373455SS — a 73GB enterprise SAS hard drive spinning at 15,000 RPM, designed for high-throughput, low-latency server and storage array environments.

The ST373455SS belongs to Seagate's Cheetah 15K.5 series, built for mission-critical applications where access speed is paramount. At 15,000 RPM with a 2ms average latency and 3.5ms seek time, it outperforms 10K RPM drives significantly in random I/O workloads. The SAS-1 (3Gbps) interface is compatible with most enterprise SAS controllers and storage arrays. Internal transfer rates up to 150 MB/s and a 16MB cache ensure consistent throughput under sustained load.
