My NAS is getting full and I need to upgrade the drives soon. Many are over 7 years old and going strong. I'm amazed that 22TB drives are a thing now and that an individual has long been able to have more movies in a computer than a whole movie rental store in times past. If you can imagine putting DVD movie cases on a shelf, think about filling a shelf about 200 feet long. That's how much data fits on one consumer drive now.
