Cool ’n’ Quiet technology controls your computer’s processor performance automatically, dynamically
adjusting the operating frequency and voltage, according to the task at hand. When an application does
not require full performance, significant amounts of power can be saved. Performance is designed to still
be responsive, with maximum processor performance being delivered when required, and automatic
power savings when possible.

About RAID Configurations
This section provides an overview of the RAID configuration you may have selected when you purchased
your computer. Your computer supports RAID level 1. A RAID level 1 is recommended for users that
desire a high level of data integrity.
The drives in a RAID configuration should be the same size in order to ensure that the larger drive does
not contain unallocated (and therefore unusable) space.
RAID Level 1 Configuration
RAID level 1 uses a data-redundancy storage technique known as mirroring to enhance data integrity.
When data is written to the primary drive, the data is also duplicated, or mirrored, on the second drive in
the configuration. A RAID level 1 configuration sacrifices high data-access rates for its data redundancy
advantages.
