HP Serial ATA Hard Drives maximize the performance of HP Business PCs by providing the technologies to meet your increasing storage demands with high-capacity drives offering superior reliability and performance. Serial ATA provides faster data transfer speeds, better system cooling airflow, more bandwidth, more headroom for speed increases in future generations and better data integrity. A next-generation technology, Serial Advanced Technology Attachment (SATA) interface connects hard drives to the PC platform enabling easy aggregation of multiple hard drives into a single PC. This offers you the additional benefits of dedicated bandwidth, the ability to more easily identify device failures and scalability- Improved protocol for enhanced data integrity. - Enhanced security prevents access to user data until one or two user-defined passwords are provided. - Performance increase to up to 3 Gb/s and 6Gb/s maximum external (burst) data transfer rate. - Thinner and smaller serial cables and connectors for easy routing and improved system cooling. - SMART IV technology constantly checks that the data flow from host interface to media and media to host interface is not compromised.
