While loops are handled very efficient by the compiler, access to arrays with a variable index is not as much so. For the PATA lib, it definitely increases speed a lot to read one sector not using a loop. For SD I'm not so sure about this, as data transfer over SPI takes its time, so the difference may be less here. But that's surely the reason for the existence of this "bad style" part: Speed.
