1.7.2 Intel® Rapid Storage Technology / SATA RAID
The PCH supports Intel® Rapid Storage Technology, providing both AHCI and integrated RAID
functionality. The RAID capability provides high-performance RAID 0 and 1 functionality on all
SATA ports. Other RAID features include hot spare support, SMART alerting, and RAID 0 auto
replace. Software components include an Option ROM for pre-boot configuration and boot
functionality, a Microsoft Windows compatible driver, and a user interface for configuration and
management of the RAID capability of the PCH.
NOTE
Intel Rapid Storage Technology / SATA RAID is only supported if an M.2 SATA SSD module is used
with the onboard SATA interface. Cannot get RAID with M.2 PCIe SSD module and onboard SATA
interface.
1.7.3 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.
1.8 Real-Time Clock Subsystem
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer
is not plugged into a wall socket, the battery has an estimated life of three years. When the
computer is plugged in, the standby current from the power supply extends the life of the battery.
The clock is accurate to ± 13 minutes/year at 25 ºC with 3.3 VSB applied via the power supply 5 V
STBY rail.
NOTE
If the battery and AC power fail, date and time values will be reset and the user will be notified
during the POST.
When the voltage drops below a certain level, the BIOS Setup program settings stored in CMOS
RAM (for example, the date and time) might not be accurate. Replace the battery with an
equivalent one. Figure 1 on page 13 shows the location of the battery.
