Internal drives
Internal drives are devices that your computer uses to read and store data. You can add drives to your
computer to increase storage capacity and enable your computer to read other types of media. Internal
drives are installed in bays.
When you install or replace an internal drive, note the type and size of the drive that each bay supports and
correctly connect the required cables. Refer to the appropriate section in Chapter 9 “Hardware installation
and replacement” on page 91 for instructions on how to install or replace internal drives for your computer.
The following illustration shows the locations of the drive bays.
Note: The computer hardware might look slightly different from the illustrations.
