I ran across this excellent summary of the status of hard disk storage vs. Solid State Drives (HDD) or Devices (SSD) from the BackBlaze.com blog entitled, "HDD vs SSD: What Does the Future for Storage Hold? — Part 2." I really can't do justice by summarizing the article, but I think anyone dealing with computers and storage needs to see that the future will hold almost unlimited storage at a very low cost. Good for genealogists.
