The Hitachi Deskstar series continues their long standing tradition of performance and quality. The T7K500 range combines both new and proven technologies to boost performance, capacity and reliability. With Hitachi's standardized features their desktop solutions are given fast transfer rates, low power and quiet accoustics. These features mean that the Hitachis Deskstar T7K500 is ideal for a host of requirements including PC systems. ATA-Entry servers, personal video recorders and other non-PC computing requirements.

Serial ATA technology provides many benefits to the end user and storage vendors by offering a platform that overcomes the limitations of Parallel-ATA drives. Integration is made simpler with Hot-Plug connection, reduced pin count, lower voltage signalling and smaller connectors and cables. SATA drives offer transfer rates of up to 300MB/Sec.
