Seagate ST3450857SS 450GB Cheetah SAS 15K RPM Hard Drive

The Seagate ST3450857SS Cheetah 15K.7 is a 450GB enterprise hard drive built for mission-critical servers, storage arrays, and high-performance computing environments that demand the lowest possible access latency from mechanical storage. Spinning at 15,000 RPM with a SAS 6Gb/s interface, it delivers sustained data transfer rates of up to 204 MB/s and an average latency of just 2.0 ms. Its third-generation perpendicular recording technology maximizes areal density, while the 16MB cache helps smooth burst operations during intensive read/write workloads.

Reliability is central to the Cheetah 15K.7's design. Seagate rates it at 1.6 million hours MTBF with an unrecoverable read error rate of 1 sector per 10^16 bits read, figures that place it at the top of the 3.5-inch enterprise drive class. The drive also incorporates PowerTrim technology, which dynamically adjusts power draw based on workload intensity, achieving a 62 percent improvement in gigabytes per watt at idle over conventional 3.5-inch hard drives. For data centers still operating SAS-based storage infrastructure, the Cheetah 15K.7 provides a proven combination of speed, endurance, and energy efficiency.
