You're right: In 2003 low end hdds' spin speed was 4200 rpm, midrange was 5400 rpm and high end were 7200 rpm...enterprise disks ran at 10,000 to 15,000 rpm...no competition for ssds' data transfer speed at all. In 2003 data transfer speed for those rpms was 20-40 mb/s or 100-500 IOPS. 2024's best ssd read/write speeds are 7,300/6,800 mb/s. No comparison at all. Like comparing a formula 1 to a horse and buggy. Laughable, but how I loved them and my dot matrix printer with its thermal paper.
