Product Description 1.5.4 SATA Interfaces The board provides nine SATA connectors, through the PCH, which support one device each: • Two SATA 6.0 Gb/s interfaces through the Intel Z77 Express Chipset with Intel® Rapid Storage Technology RAID support (blue) • Two SATA 6.0 Gb/s interfaces through a Marvel 88SE9172 controller (gray) • One back panel eSATA 6.0 Gb/s port through a Marvel 88SE9172 controller (red) • Four internal SATA 3.0 Gb/s interfaces through the Intel Z77 Express Chipset with Intel Rapid Storage Technology RAID support (black) The PCH provides independent SATA ports with a theoretical maximum transfer rate of 6.0 Gb/s for five ports and 3.0 Gb/s for four 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. For more information, see: http://www.serialata.org/.

1.5.4
SATA Interfaces
The board provides nine SATA connectors, through the PCH, which support one device
each:
•
Two SATA 6.0 Gb/s interfaces through the Intel Z77 Express Chipset with Intel
®
Rapid Storage Technology RAID support (blue)
•
Two SATA 6.0 Gb/s interfaces through a Marvel 88SE9172 controller (gray)
•
One back panel eSATA 6.0 Gb/s port through a Marvel 88SE9172 controller (red)
•
Four internal SATA 3.0 Gb/s interfaces through the Intel Z77 Express Chipset with
Intel Rapid Storage Technology RAID support (black)
The PCH provides independent SATA ports with a theoretical maximum transfer rate of
6.0 Gb/s for five ports and 3.0 Gb/s for four 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.

SATA RAID
The board supports the following RAID (Redundant Array of Independent Drives) levels
via the PCH:
•
RAID 0
- data striping
•
RAID 1
- data mirroring
•
RAID 0+1 (or RAID 10)
- data striping and mirroring
•
RAID 5
– distributed parity
