A volume is a logical area on a device that allows data to be written and read. It is typically represented in your computer’s operating system as a drive with a letter and can be sub-divided into files and folders. For example, on a typical home computer the logical volume that exists on the hard drive that hosts the Windows operating system is most often labeled the “C” drive. A device can contain a single logical volume or it can be partioned into multiple logical volumes. Futhermore, with the assistance of a logical volume manager, a logical volume can span multiple devices.
