SATA Interfaces

The board provides six SATA connectors through the PCH, which support one device
per connector:
• Two internal SATA 6.0 Gb/s connectors (blue)
Two internal SATA 3.0 Gb/s connectors (black)
•
• One internal eSATA 3.0 Gb/s connector (red)
One eSATA 3.0 Gb/s connector on the back panel for external connectivity (red)
•
The PCH provides independent SATA ports with a theoretical maximum transfer rate of
6 Gb/s for two ports and 3 Gb/s for four ports. A point-to-point interface is used for
host to device connections.
The underlying SATA functionality is transparent to the operating system. The SATA
controller can operate in both legacy and native modes. In legacy mode, standard IDE
I/O and IRQ resources are assigned (IRQ 14 and 15). In Native mode, standard PCI
Conventional bus resource steering is used. Native mode is the preferred mode for
configurations using the Windows* XP, Windows Vista*, and Windows 7* operating
systems.
NOTE
Many SATA drives use new low-voltage power connectors and require adapters or
power supplies equipped with low-voltage power connectors.
