One thing that has been on my mind lately is how much more capacity and speed SSD have gained over the years relative to their price. You can now acquire an SSD with 1TB of storage for under a a $100 on amazon! As these become cheaper and easier to make it makes me wonder how much longer computers will use the slower and more fragile HDD’s and when will they go the way of magnetic tape and only have use for mass storage. The only advantage they have is their cost to capacity ratio and I do not foresee that lasting much more than a decade or so if SSD’s continue to go down in cost. What sorts of media will be lost in 50 years when HDDs are so uncommon that you can no longer find a device that uses them any more.
