Most external drives should be fine. The only thing you need to be careful when choosing is does it support my connection type. Depending on your computer you may have USB 2.0. Newer models have USB 3.0 or 3.1. The newer are faster data transfers speeds. To be safe make sure the drive you are looking at can support both the 2.0 and 3.0 connection types. Hint USB 2.0 connector is white inside the 3.0 connector is blue inside.
