Hitachi / HGST HUS724030ALA640

Enterprise class, 7200RPM, 3TB SATA 6.0Gb/s, 64MB Cache hard drive for high-capacity nearline environments! Enterprise Grade Hard Drive! The HGST Ultrastar™ 7K3000 is the world’s first and only 7200 RPM hard drive rated at 2.0 million hours MTBF. The Ultrastar 7K4000 represents the fifth-generation HGST 5-platter mechanical design, and has been field proven by top server and storage OEMs as well as leading Internet giants. When the highest quality and reliability are a top requirement, customer field data proves that the Ultrastar 7K4000 delivers by reducing downtime, eliminating service calls and keeping TCO to a minimum. Engineered for the highest reliability, the Ultrastar 7K4000 is not only put through grueling design tests during development but must also pass stringent ongoing reliability testing during manufacturing. Across the entire Ultrastar family, world-class quality control, combined with scientific root-cause analysis and multi-faceted corrective actions, ensure that HGST remains the recognized leader in quality and reliability for enterprise-class hard drives.

This MTBF rating is based on a sample population and is estimated by statistical measurements and acceleration algorithms under nominal operating conditions. MTBF ratings are not intended to predict an individual drive’s reliability. MTBF does not constitute a warranty. CAPACITY: One MB is equal to one million bytes, one GB is equal to one billion bytes and one TB equals 1,000GB (one trillion bytes) when referring to hard drive capacity. Accessible capacity will vary from the stated capacity due to formatting and partitioning of the hard drive, the computer’s operating system, and other factors. Advanced Format drive: 4K physical sectors with 512 emulation BUFFER: Portion of buffer capacity used for firmware. SEEK: Excludes command overhead MB/s: Based on 1,000,000 bytes per second.
