Maximize SATA Value with SAS Controllers
Remarkable cost-effectiveness has always been the hallmark of Serial ATA (SATA) disk drives

To that end, SAS cables, connectors, HBAs, and RAID controllers are fully compatible with SATA and SAS drives. Furthermore, SAS controllers seamlessly identify and communicate with SATA devices, making a SAS controller just as efficient at issuing SATA commands as a SATA controller.
SATA and SAS play distinctly different roles in the enterprise.
The two technologies are complementary rather than competitive, with SATA disk drives optimized for low cost/GB and SAS drives built for transactional, high-availability applications. Together they can efficiently meet a broad spectrum of enterprise storage needs in a single infrastructure. Though this is a primary objective of the Adaptec Unified Serial Architecture, the benefits don’t end there.
SAS/SATA for Maximum SATA Value
While the ability to intermix SAS and SATA drives in the same infrastructure represents a quantum leap in storage efficiency, Unified Serial Architecture pays equally compelling dividends in storage solutions that utilize only SATA disk drives.Most SATA drive-based storage solutions can be divided into three basic configurations: direct-attached consisting of a one-to-one connection in the server; an internal backplane in the server; and an external backplane on a JBOD.
