what does raid mean
Best Answer: Raid is an acronym that stands for Redundant array of independant disks. Below are some RAID configurations with a brief description. RAID 0 This configuration is the fastest of all the RAID levels, it uses a technique called data striping (see below) and requires at least 2 hard disks. RAID 1 This level uses a pair of hard disks at a time to provide fault tolerance (there is no performance benefit) and requires at least 2 hard disks.
