Sata Interfaces; Sata Raid - Intel DP55WB - Media Series P55 micro-ATX Core i7 i5 LGA1156 Desktop Motherboard Specification

1.6.2

SATA Interfaces

The board provides six internal SATA connectors through the Intel P55 Express
Chipset, which support one device per connector.
The Intel P55 Express Chipset provides independent SATA ports with a theoretical
maximum transfer rate of 3 Gb/s per port. One device can be installed on each port
for a maximum of six SATA devices. A point-to-point interface is used for host to
device connections, unlike Parallel ATA (PATA) IDE which supports a master/slave
configuration and two devices per channel.
For compatibility, 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 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.

SATA RAID

The board supports Intel Matrix Storage Technology which provides the following RAID
(Redundant Array of Independent Drives) levels via the Intel P55 Express Chipset:
• RAID 0 - data striping
• RAID 1 - data mirroring
• RAID 0+1 (or RAID 10) - data striping and mirroring
• RAID 5 - distributed parity
NOTE
In order to use supported RAID features, you must first enable RAID in the BIOS. Also,
during Microsoft Windows XP installation, you must press F6 to install the RAID
drivers. See your Microsoft Windows XP documentation for more information about
installing drivers during installation. Both Microsoft Windows Vista and Microsoft
Windows 7 include the necessary RAID drivers for both AHCI and RAID without the
need to install separate RAID drivers using the F6 switch in the operating system
installation process.
