Intel Desktop Board DH77DF Technical Product Specification 1.5.4.1 SATA RAID The board supports Intel Rapid Storage Technology which provides the following RAID (Redundant Array of Independent Drives) levels via the Intel H77 Express Chipset: • RAID 0 - data striping • RAID 1 - data mirroring • RAID 0+1 (or RAID 10) - data striping and mirroring • RAID 5 - distributed parity 1.5.4.2 Intel® Smart Response Technology Intel® Smart Response Technology is a disk caching solution that can provide improved computer system performance with improved power savings. It allows configuration of a computer system with the advantage of having HDDs for maximum storage capacity with system performance at or near SSD performance levels. For more information on Intel Smart Response Technology, go to http://www.intel.com/support/chipsets/sb/CS-032826.htm NOTE In order to use supported RAID and Intel Smart Response Technology 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. Microsoft Windows 7 includes 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. 28

Intel Desktop Board DH77DF Technical Product Specification

1.5.4.1

SATA RAID

The board supports Intel Rapid Storage Technology which provides the following RAID

(Redundant Array of Independent Drives) levels via the Intel H77 Express Chipset:

•

RAID 0

- data striping

•

RAID 1

- data mirroring

•

RAID 0+1 (or RAID 10)

- data striping and mirroring

•

RAID 5

- distributed parity

1.5.4.2

Intel

Smart Response Technology

Intel

Smart Response Technology is a disk caching solution that can provide improved

computer system performance with improved power savings. It allows configuration of

a computer system with the advantage of having HDDs for maximum storage capacity

with system performance at or near SSD performance levels.

NOTE

In order to use supported RAID and Intel Smart Response Technology 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.

Microsoft Windows 7 includes 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.
