Please ELI5, I know what each of these words mean in isolation but I know nowhere near enough about storage to understand what this means as a sentence.

- hinkley 6y agoHard drive only have a handful of different rates of spinning (rpm). The diameter of the platters are also limited to a couple options. The number of platters varies a bit, but there are numbers that are too stupid-low and ones that are too high to fit into the case, so there are maybe 3-5 varieties? If you have two drives with the same number of platters, the same diameter, and the same rotation speed, the one with the highest storage can only do that by increasing storage density - making the bits smaller. Smaller bits means more tracks, but also more bits per track. So in a single rotation (1/7200 of a second, for instance), the read head sweeps across more data. If it reads it as fast as it sees it (which they do), then that means a higher transfer rate.
