The first hard drive offering 1 TB of storage was released by Hitachi in 2007. The drive cost $399 ($.40 per GB), and was offered to computer manufacturers, as an upgrade for technically-inclined PC owners, and for use as an external storage device. In 2015, the same drive can be had for less than $100 on Amazon, and competition in the storage industry has reduced the typical cost per GB to around $.05.
