Most computers come with at least 40 to 80 GB of disk space, which may be insufficient for some users. Disk enclosures can provide the additional storage needed for a device. Other than disk space and external connectivity, disk enclosures also have the following advantages and capabilities:

They can be easily connected to video game systems and digital multimedia recorders
They can add redundant array of independent disk (RAID) capabilities to computers that do not have RAID controllers
They allow non-networked computers to easily transfer data from one computer to another
They add a removable backup capability with a distinct power source from the connected computer
They reduce cooling requirements inside the computer
They support hot swapping with an inexpensive and simple configuration
They provide physical protection for hard drives

Different enclosures are available in the consumer market. These include FireWire, USB, optical disk drive and magnetic hard drive enclosures.
