Im sure your laptop has USB ports cause that is all you will need. If you have a newer Laptop your USB ports should be 2.0 which is better for tansfur rate. Are you just getting an external HDD or a HDD and caddy? Either way you should be fine as long as you dont run the OS (operating system) from it for your laptop, but storage wise it should be okay, I run a 250gb caddy hdd and ive had no problems.
