There are many parameters that could be used to describe disk performance; Which of the following statements is most true? Note: none of the statements may be true exactly, but one will always be much closer to the truth than the other three. Also note: you should assume all dimensions and parameters of the disk are unchanged except for the ones mentioned. a) If you double the number of sectors per block, then you halve the capacity of the disk. b) If you double the rotational speed of the disk, then you halve the average rotational latency. c) If you divide tracks into half as many blocks, then you double the read time for a block. d) If you double the number of bits per track, then you double the average rotational latency.
