HPE 72GB, 10k, SAS internal hard drive 10000 RPM 2.5"

72.0GB hot-swap single-port Serial Attached SCSI (SAS) hard drive
Serial Attached SCSI is the logical evolution of SCSI, including its long-established software advantage and the Serial ATA 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. As the technology evolves, device support will be further enhanced, making it an even more attractive alternative for enterprise users who want a solution far superior and more flexible than any other storage technology. The results of aligning the Serial Attached SCSI and Serial ATA technologies to serve storage users, who need large capacity at a lower cost, will provide even greater choice to the storage industry.
