Consider a disk drive device with block size 512 bytes and data transfer rate is 512 bytes/msec. The disk drive rotates at a speed of 2400 RPM (rotations per minute). The average seek time is 30 msec.
Calculate the average time it would take to transfer 10 random blocks on disk and compare it with the time it would take to transfer 10 consecutive blocks on the same track.
