Create Multiple Partition Easily

Disk partitioning is logical division of a hard disk drive into multiple storage units, which are known as partitions. Disk Partitioning divides a hard disk drive logically into multiple units, which treats one physical disk drive as multiple disks.
Creating multiple partitions has the following advantages:
  • Multiple partitions separate the operating system (OS) and program files from user files. This permits a user to backup (or clone) only the operating system and the installed software.
  • Computers with multiple partitions have a separate area for OS virtual memory swapping/paging.
  • Partition keeps frequently accessed programs and data at closer memory locations.
  • It separates cache and log files from other files. These files change size dynamically and rapidly, and can potentially fill a file system.
  • Multiple partitions allow users to have more than one operating system on a single computer. For example, you could install Linux, BSD, or Microsoft Windows in addition to your Mac OS X operating system on different partitions of the same hard disk and can choose the operating system at start-up.
  • A partition protects or isolates files and makes it easier to recover a corrupt file system or operating system installation. If one partition is corrupt, other partitions (and file systems) may not be affected.
  • Partition raises the overall computer performance on systems where smaller file systems are more efficient.
  • Partitioning a hard disk into smaller sized volumes significantly reduces the time needed for diagnostic tools such as Check Disk to run or for full image backups to run.
Disadvantages of having more than one partition, as compared to having a single partition on the same hard disk are as follows:
  • Partitioning reduces the total space available for user storage. It causes certain file system administration areas of each partition to be duplicated.
  • It reduces overall disk performance on systems where data is accessed frequently and parallelly across multiple partitions.
  • Partitioning increases disk fragmentation as the average size of continuous free blocks on each partition is reduced as compared to a single partition of the same size.
  • It prevents using the full disk capacity, because it may scatter the free space apart.
  • It slows down the movement of data across different partitions of the same hard disk.
  • Partitioning hurts portability and imposes constraints on how entities are linked to each other in a file system.

A hard disk drive (HDD) is a data storage device used for storing and retrieving digital information using rapidly rotating discs (platters) coated with magnetic material. A HDD retains its data even when its power is turned off. Data is read in a random-access manner in a HDD.

A volume is a single accessible storage area with a single file system. Although a volume is different from a physical disk drive and is accessed with the operating system's logical interface. Volumes are logical separations of the hard drive.


A partition is a part or section of the hard drive, which is treated by the operating system as an independent storage area or drive. For example, a 120-gigabyte (GB) drive can be divided into several partitions, rather than being used as one large drive. Partitions are logical separations on the hard drive, mostly created by the user during installation of an operating system.

The terms; partition and volume are often interchangeable and for most purposes, the end user does not need to understand the difference.

Partition management is the process of managing the partitions of a computer by primarily performing disk operations, such as creation, deletion, resizing, and formatting of partitions. Stellar Partition Manager is an example of Mac-based disk partition management software.

Stellar Partition Manager is professional Mac volume (partition) manager software that allows you to perform disk operations, such as creating, deleting, resizing, formatting, and hiding/revealing a Mac partition.
