Product Description 1.6.3 SATA Interfaces The board provides six SATA connectors through the PCH and one eSATA connector through a Marvell controller, which support one device per connector: • Two internal SATA 6.0 Gb/s connectors (blue) • Four internal SATA 3.0 Gb/s connectors (black) • 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 6.0 Gb/s for two ports and 3.0 Gb/s for five 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. For more information, see: http://www.serialata.org/.

1.6.3
SATA Interfaces
The board provides six SATA connectors through the PCH and one eSATA connector
through a Marvell controller, which support one device per connector:
•
Two internal SATA 6.0 Gb/s connectors (blue)
•
Four internal SATA 3.0 Gb/s connectors (black)
•
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
6.0 Gb/s for two ports and 3.0 Gb/s for five 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.
