1.5.4 SATA Interfaces
The board provides six SATA connectors, through the PCH, which support one device
each:
• Two SATA 6.0 Gb/s interfaces through the Intel H77 Express Chipset with Intel
®
Rapid Storage Technology RAID support (blue)
• Two internal Serial ATA (SATA) 3.0 Gb/s interfaces through the Intel H77 Express
Chipset with Intel Rapid Storage Technology RAID support (black)
• One internal mSATA port (PCI Express Full-/Half-Mini Card slot)
• One back panel eSATA port (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 PCH supports the Serial ATA Specification, Revision 3.0. The PCH also supports
several optional sections of the Serial ATA II: Extensions to Serial ATA 1.0
Specification, Revision 1.0 (AHCI support is required for some elements).
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 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.
