Compaq hard drives are provided with the reliability and functionality needed for today's systems. All hard drives are designed and tested for compatibility and interoperability in the systems for which they are intended in order to provide the immediate, flawless integration expected from Compaq equipment.

Serial Attached SCSI (SAS) is the logical evolution of SCSI, including its long-established software advantage and the Serial ATA (SATA) electrical and physical connection interface. With enterprise storage requirements escalating and becoming more complex, factors such as larger capacity, greater density, security, scalability and accessibility are more critical than ever. Enterprise data centers must be online all the time, fulfill requests from numerous users simultaneously, allow for constant growth and expansion and be maintained while in operation. Serial Attached SCSI meets all these demands while providing the highest performance.Minimize
