With just a little attention to sector interleave, in fact, the Apple Disk II was capable of streaming from the floppy into memory at the full rotation speed of the disk. It wasn't actually possible to be faster at all, without a hardware modification to the drive motor. And it was all done with a "controller" card build out of like eight chips you could get at Radio Shack. The Disk II really is probably the cleverest single piece of hardware shipped in the microcomputer era.
