A logical disk is a concept from computing. Logical disks provide a certain amount of space to store data. Unlike real (called physical) hard disks that can be touched, logical disks can take this storage space from different locations.
Common locations where this can be taken from:
- A disk partition on a hard disk
- A logical volume from a logical volume manager
- A combination of hard drives (as in a RAID system, which contains the physical disks)
- A storage area network
- The main memory of a computer (this can be used for temporary files, which can be deleted when the system shuts down)
The disk is described as logical because it does not actually exist as a single physical entity in its own right.
