Logical disks divide computer memory into separate units for better organization and functionality. Physical devices are unformatted and need partitioning. Logical disks can store different operating systems and prevent memory corruption and data access by unauthorized users.
A logical disk is a type of computer storage method in which memory is partitioned to create a separate disk of allocated memory. Unlike physical memory, or a physical device that can be touched, logical memory is divided into multiple sections to allow users to store information in these individual units. This is because using all of the computer’s memory for a single drive is usually impractical and makes it difficult for the user to organize information. Advanced users can install completely different operating systems (OS) on the logical drive to increase the functionality of the computer.
When a computer user first receives a physical storage device, such as a hard drive, it arrives unformatted. This means that memory is one large unit and has no drive separations. After the user installs the new storage device, the computer will partition the data into different drives, such as a C: drive, where most of the data is stored, and similar drives.
A physical device can include many logical disk partitions. The amount of memory stored on a partition and the amount of logical disks are not limited by anything except the amount of memory on the storage device. While there is technically no minimum amount of memory required for a logical disk, the common default is 2 gigabytes (GB), as this is the minimum amount of memory required for system functions.
Both ordinary and advanced users often experience the benefits of a logical disk. On the common side, it allows a user to keep data organized across different facets, such as home and work. This also allows the user to keep files that are not compatible with each other in different drives.
On the advanced side, one logical disk can be used to store an entirely different operating system on the logical disk. For example, if the user is running the Macintosh® operating system, a Windows® operating system can be installed on another logical partition. This allows the user to run a wider range of programs and experience the benefits of both operating systems on the same computer.
Another benefit associated with using logical disk architecture is memory stability. When computer memory is tagged under a disk, the tendency for memory corruption and fragmentation increases exponentially. If your computer is made up of slices, this prevents your memory from experiencing these problems. Data is also more secure because administrators can prevent users from accessing information on other logical drives unless they achieve a higher level of access.
