So althoguh the disk is spinning at half the speed... the data rate is the same... suggesting that you would not notice any slow down... hmmm, I imagine seeking time would be increased though :-(

Well, there is twice as much data for each track, so each read and write operation needs twice as long. Although the same amount of data is transferred in the same time, you feel as if it is slower because you usually measure floppy speed by the track clicks. And certainly you need twice as long to format 1760KB than to do it with only 880KB.
