Serial Attached SCSI (SAS) provides a superior storage solution. With some storage requirements increasing and others becoming more complex, factors such as flexibility, performance, increased reliability, higher density, security, scalability, and accessibility are more critical than ever. Organizations today consist of different types of environments. Enterprise data centers must be online 24/7, meet the requests of many users simultaneously, and allow for constant growth and expansion while in operation. Other customer environments require high capacity storage and high data availability for low I/O environments. HP's portfolio of SAS drives meets all of these demands.
