Curiously I seem to be using less storage space as time goes by. I recently upgraded my computer by going over to using solid state drives. I replaced two, three terabyte drives, with two 256 gigabyte drives. Performance tripled. But what surprised me the most was how little of that space I ended up using. Almost all of my storage is now on line. Also, subscription services such as Netflix, Spotify and Audible have broken my torrenting habit, as well as putting an end to accumulating CDs and DVDs. Nevertheless, I dare say that new storage media will become popular if it provides speed of access.
