expired HP 500GB USB 3.0 2.5" Portable Hard Drive $59 Delivered
Pretty good price for a USB 3.0 HDD delivered.
Sorry if the description is too short but there isn't really much else to say. All the information you need is in the title.
And HP hard drives aren't as bad as their computers (at least from my experience). I have a 120GB portable from 2007 and it is still going strong.
