Although you may feel tempted to buy the biggest hard disc drive you can get, there is a point at which the latest, Hard Dischighest capacity, latest technology disc drives start to get more expensive per capacity. A way to think about this is to look at the hard disc drive storage devices available and their prices, and to divide the size of the drive by the cost, for each one.
