Dynamic Volumes - Simple Volume

Windows Server 2003 dynamic storage supports five dynamic volume types: simple
volumes, spanned volumes, striped volumes, mirrored volumes, and RAID-5 volumes.

The most basic type of volume on a dynamic disk, a simple volume. A simple volume is the equivalent to a basic disk partition. Simple volumes can span space only on a single disk and are represented as single logical volumes. You can extend simple volumes to unallocated space on the same disk. Simple volumes are not fault tolerant and provide no redundancy.
