I had the same issue a month ago on trying to decide for an externalHD for a new notebook, I went with the Hitachi SimpleTough. I have to mention that this HD is by far the most indestructible external hard drive Ive seen, capable of surviving drops of up to 10 feet and up to one ton of pressure. With a built-in USB cable, two-tiered data security package, and an impressive three-year warranty, I have no issue recommending this external hard drive to shoppers looking for space and security.
