About Your RAID Configuration

This section provides an overview of the RAID configuration that you might have selected when you
purchased your computer. Although several RAID configurations are available, Dell offers either a RAID
level 0 configuration or a RAID level 1 configuration for the Dell™ XPS™ M2010 computer. A RAID
level 0 configuration is recommended for high-performance computing and gaming, and a RAID level 1
configuration is recommended for the data integrity requirements of digital photography and audio.
®
The Intel RAID controller on your computer can only create a RAID level 0 configuration using two
physical drives.
NOTE:
RAID levels do not represent a hierarchy. A RAID level 1 configuration is not inherently better or worse than
a RAID level 0 configuration.

RAID Level 0 Configuration

A RAID level 0 configuration uses a storage technique known as "data striping" to provide a high data
access rate. Data striping is a method of writing consecutive segments, or stripes, of data sequentially
across the physical drives to create a large virtual drive. Data striping allows one of the drives to read data
while the other drive is searching for and reading the next block.
