A) Tapes
B) Hard disk
C) Floppy disks
D) CDs
E) None of these
Correct Answer: B
Solution :
I lard drives arc fastest among given options. Magnetic tapes are sequential access devices. Hard disks hold more data and are faster than floppy disks, their disks spin faster. Also.

In part be-cause the laser reads pits and lands one bit at a time. Also optical disk is split into sector. So rotational speed is slow.
