Serial Attached SCSI (SAS) offers a superior storage solution. As some storage demands increase and others become more complex, factors such as flexibility, performance, enhanced reliability, higher density, security, scalability, and accessibility are more important than ever. Today's organizations consist of various types of environments. Enterprise data centers need to be online nearly around the clock, handle requests from numerous users simultaneously, and allow for continuous growth and expansion during 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 these requirements.
