The drive hardware can only read or write a single task at a time
because of positioning the heads to specific sectors.

You can have multiple tasks executing which can read or write from the
drive if your operating system allows multitasking. The queueing of
these requests may result in slower overall time than a single serial
job but it depends a lot on exactly what you are trying to do.
