Disk drives have been getting larger. Their capacity is now often given in terabytes (TB) where 1 TB = 1000 gigabytes, or about a trillion bytes. A search of prices for external disk drives on Amazon.com in early 2014 found the following data:

6.0 …………………………… 423.34
8.0 …………………………… 596.11
12.0 …………………………… 1079.99
32.0 …………………………… 4461.00
