Storage peripherals

An external hard drive will provide maximum data storage. It works the same as a normal hard drive but is portable and holds a huge amount of data (some can store over 1,000 GB).

DVDs and flash memory cards can hold much more, between 4-8 GB, and this is likely to increase over time.

CDs and zip disks hold about 700 MB of data.

Cloud storage – you pay a monthly fee to store your data online
