In my youth I purchased a second hand C64 it came with around 300 games and a disc drive but also a tape drive with a number of tapes,since the tapes had some games not on my discs I tried the tape drive, it took around ten minutes to load a game into the 64K memory the vast majority games loaded fully into memory. some worked in a similar way to future games with multiple discs,where the game stopped and you manually loaded another tape went and had a bath made a cup of coffee walked the dog and then continued the game, asset loading came much later mainly due to HD's
Never had the tape drive, but my friend had one... I hated it for being so slow.
My 1571 floppy drive was much faster, especially in combination with my fast loader cartridge "Final Cartridge III":
