Serial ATA Hard Drives maximize the performance of HP Business PCs and Workstations. These high-capacity drives offer superior reliability and performance. Serial ATA is the next generation ATA interface. It provides faster data transfer speeds, better system cooling airflow, more bandwidth, more headroom for speed increases in future generations and better data integrity improving productivity. A next-generation technology, Serial Advanced Technology Attachment (SATA) interface connects disk drives to the PC platform. SATA point-to-point topology provides a direct path between the disk drive and the PC enabling easy aggregation of multiple disk drives into a single PC. This offers you the additional benefits of dedicated bandwidth, the ability to more easily identify device failures and scalability.
