2 TB External Hard Drive
73What is a 2 TB External Hard Drive?
External Hard Drives are hard drives designed to be plugged or installed outside of the computer case. They simply sit beside the computer and plugged to the computer using a short length of interface cable. They are generally installed by using a USB (Universal Serial Bus) or a firewire interface cable.
Just for comparison, there are hard drives that are called Internal Hard Drives, because they need to be installed inside the computer case, necessitating the opening of the computer case in order for them to be installed.
External hard drives can either be a Desktop or a Portable drive. Portable types are designed to be smaller than the Desktop ones, and they are meant to be carried around from one place to another.
Hard drive disk space capacities, which is a measure of how much information a certain hard drive can store, is expressed in MB (Mega Byte), GB (Giga Byte), and TB (Tera Bytes). A Megabyte is equal to 1 milllion bytes, while a Gigabyte is equal to 1 billion bytes, and a Terabyte is 1 trillion bytes. Also, 1000MB is equal to 1GB and 1000GB is 1TB.
Below are examples of 2TB External Hard Drives.

A useful hub.
Portable external hard drives are generally more expensive per gigabyte than internal hard drives.
I have seen a cradle that allows an internal hard drive to be connected to a computer as if it were an external drive
Note that you never get quite the quoted capacity since some space is taken up for disk driver software
Not also that some laptops limit the power a device can draw from the laptop and these either need an external power supply or will take up two USB ports
If using an external hard drive for backups remember the drive will hold your sensitive data and guard it as carefully as your laptop
