1. Assume the following specification for a hard disk drive

Rotation Speed: 7,200 rev/min

Arm movement Time: 0.5 msec fixed startup + 0.05 msec for each track crossed. (Startup is constant no matter how far the arm moves.)

Surfaces: 2 (The disk has two sides and a single arm holds both of the read/write heads)

Average Moves: On average the read/write head moves only 30 tracks

Tracks per Surface: 500

Sectors per Track: 20

Characters per Sector: 1024

a) How many characters can be stored on this disk?

b) Create a best-case, worst-case, average-case access time table that shows each of seek, latency, transfer and average access times
