Probably just over a decade ago, my organisation bought me a thumb drive, which had a capacity of 100 Megabytes (Mb). I used it to transfer large files between work and home so I could work on them at home. At the time, that thumb drive cost $179. That comes to about $1.79 per Mb. Now you can buy a 64 Gigabyte (Gb) thumb drive for $20. At the rate of the original thumb drive, 64 Gb of storage would cost about $114,000. Even more extreme is the fact that a week ago, I bought a 2 Terabyte (Tb) external hard drive as a backup system for $89. Given that 1 Tb is 1000 Gb, and a Gb is 1000 Mb, then 2 Tb is equivalent to 2,000,000 Mb. If I had tried to buy that much storage space at the price of the original thumb drive, it would have cost me $3.58 million. Digital storage is a hell of a lot cheaper than it used to be.
