No, when the disk receives a write command, it accepts the write data
immediately (up to some large limit). That way, when the heads settle
on the track, if the disk happens to be positioned in the middle of the
transfer, it can write the last part of the data to the disk
immediately, then wait for the disk to spin to where the transfer starts
to finish the transferring the first part of the write data. This
reduces average latency, i.e. improves performance.
But it requires reordering of writes.
