RAID canalso prevent data loss in case of a drive failure by reconstructing (or rebuilding) the missing data from thefailed drive using the data from the remaining drives.RAID array (also known as RAID drive group) is a group of multiple physical drives that uses a certaincommon method to distribute data across the drives. A virtual drive (also known as virtual disk or logicaldrive) is a partition in the drive group that is made up of contiguous data segments on the drives. Virtual driveis presented up to the host operating system as a physical disk that can be partitioned to create OS logicaldrives or volumes.An introduction to RAID is available at the following Lenovo Press website:https://lenovopress.lenovo.com/lp0578-lenovo-raid-introductionChapter 5.
