I’ve worked my way through quite a few hard drives over the years. When I bought my first computer, a NEC APC. I had the option to buy a 10MB drive for about $5,000. I opted not to spend that much for a hard drive that was only 10 times the capacity of the 8″ floppies it used. My phone now has a 128GB micro SD card that can be bought for $20. That’s roughly 13,000 times the capacity for 1/250th the price or about 3.25 million times the storage per dollar. I have two 5TB and two 6TB drives in my main work computer that cost a little over $100 each, more than 20 million times the storage per dollar. What I really need to do it make sure there is nothing left on any of these drives that I need and then destroy them. But like so much of what needs to be done, it takes time.
