I mean I can basically loosen an external hard disk and insert it in a laptop but will it work as well as internal ones? What makes them different?

They have a case. There is no technical difference in the hardware except that external HD have a case and an USB connector. –  Uwe Plonus Jun 13 '13 at 13:48
@OlayinkaSF - Often there is no difference often the exact same model you can purchase as an interal drive is used. There are also some exxternal drivers that are smaller. –  Ramhound Jun 13 '13 at 13:48

Nothing internally, the only difference is the connection between it and your computer.

There is no difference.

If you open an external harddrive you will find a Firewire or USB to SATA convertor and a regular SATA harddisk.
