If you can, try and get an internal drive over an external drive, they're better and more reliable. You should also try and look for a 'portable drive' more so than an 'external drive', external drives require a power source, portable drives do not, that is what makes them portable, instead of being labeled 'external', which are actually internal driver with adapters and such to make them work on the outside of the computer with a USB cable to transfer the data.

Desktop Drives need external power source, be cautious in what you need.

Western Digital = The Best
Seagate = The Good
Others = The sucky poo poo ... xD

Go for WD if you can, but seagate are pretty good also
