Brings back great memories of Sierra’s King’s Quest and swapping out floppies as you reach different parts of the game. 2 seconds was definitely the minimum time I would imagine being able to put in a new floppy and not risk crushing it, but doesn’t that not take into account the ability of the hardware to find the sectors on the disk that need to be calibrated when you insert it?

There is no calibration in floppies (and very old hard drives), track location is hardcoded in hardware and selected with stepper motor.

Hard-sectored 8" and 5.25" floppies did exist.
