I still remember my 2gb HDD I was so excited... I'm feeling rather old right now.
Was starting with 240-260 MB drive, that has failed after 4-5 months, as a complete series of that drives was faulty.... remember wingcommander on 12 3,5 disk, as what the hell is it for a game :-D
Just think you can pick up flash drives for little to nothing, that out perform any of the 3.5" drives of the 90's. Looking at all the advancements in SSD, I can vividly see the end of HDD storage. It may take another 20 years but HDD will see end-of-life.
My first RAM buy was an upgrade for a Kim-1; about $240 for 8K - that's Kilobytes. 4 Megabytes would have cost $120,000. Of course, the power supply to run 500 of those boards would dim the house lights - probably 100 amps. Wow, have we come a long way. 10 TB drives - that's 500,000 times the size of the AT drive of 1984, only 30 years ago. One drive holds more than all the 20 MB IBM PC/AT drives sold that year by a wide margin - maybe more than all the drives (PC-class) sold in total to that point.A little off topic of HDD but I remember buying a 4Mb stick of Ram for $1600
