A magnetic disk drive has the following characteristics:
• 10,000 rpm spin rate
• 2 ns head-to-head switching time
• 3 ?s average track-to-track seek time
• 5 platters, 1024 tracks/platter side recorded on both sides, 50 sectors per track on all tracks
Questions:
a. What is this drive s storage capacity?
b. How long will it take to read the drive s entire contents sequentially?
c. What is this drive s serial access time?
d. What is this drive s average (random) access time (assuming movement over half the tracks and half the sectors in a track)?
