SAS disk drives
The I/O evolution is Serial Attached SCSI
Boasting features that liberate SCSI from its parallel predecessor, Serial Attached SCSI (SAS) delivers new levels of breakthrough speed and connectivity while retaining the functionality and reliability that has made SCSI the premier enterprise storage I/O standard for over two decades. By melding serial performance and scalability with existing SCSI environments, SAS adds new freedom to storage solutions while maintaining the long-standing foundation on which enterprise storage was built.

Spotlight: Rationalizing the Data Center
During the boom years of the late Nineties, investment in enterprise IT infrastructure seemed limitless. When the economic bubble eventually burst, however, the true cost of those spending sprees became clear. As a result today's IT managers are taking a more prudent, far-sighted approach to enterprise storage planning. In this article, the second in a monthly series of technology papers Seagate plans to publish, we examine how Serial Attached SCSI (SAS) can lead the way towards a new era of storage rationalization and efficiency.

SAS delivers powerful and consistent performance. SAS accelerates storage performance by utilizing a full duplex, point-to-point architecture to achieve reliable data rates of 3.0 Gb/s, and by adopting the most advanced command queuing for handling intense enterprise traffic.
SAS protects your pocket book. SAS preserves IT investments in storage management and enterprise application software by integrating the same SCSI commands that support enterprise storage environments today, and by eliminating any need for system-level workarounds like those required for ATA.
SAS opens new possibilities for your IT infrastructure. SAS liberates storage from prior scalability restrictions of its parallel predecessor by using expanders to aggregate hundreds of drives while preserving performance.
SAS is I/O friendly. SAS back planes and host bus adapters enable compatibility between enterprise-class and desktop-class drives, providing system integrators and IT departments with greater flexibility in choosing the right drive for their applications.
