It is the process of dividing the storage space of a hard disk drive into multiple storage units. Each separate storage space is called partition. After partition, one can use one physical disk as multiple disks. A partition editor program is used for creating, deleting or modifying partitions. The procedures are specific to operating systems.
Benefits of disk partition:
Helps in formatting disk conveniently: If you have separate disk for separate data type, you need not copy the data extensively, if you need to format a drive since relevant data resides in another partition. One can just format the disk which is malfunctioning.
High level of security: If there is a virus attack or malware attack in one single disk, they will not spread to other disks. Also, users can quickly scan/format the infected storage area and protect the whole system from virus/malware.
Keep data organized: By partitioning disk drive, one can keep data organized. There is separate drive for specific data group. So, one can keep all data in a very organized manner.
Easy back-up: If back-up is required for any reason, you don’t need to make back-up of whole disk. Just take back-up of the drive, in which important data is kept.
Detriments of disk partition:
Slow movement of data: It takes longer time to move data from one partition to another as compared to time taken in moving data in the same partition.
Loss of space: There is loss of some space with every partition. So, it is not advisable to make many partitions.
