  46. 7,200 rpm = 120 rps. 1/120 = 8.333 msec
      Average is 1/2 revolution: 4.17 msec
      10,000 rpm: 3 msec
  47. Center: 1.35 MB/sec * 1/1600 min/rev * 60 sec/min =  50.6 KB
      Outer:  1.35 MB/sec * 1/570  min/rev * 60 sec/min = 142.1 KB
  48. 30 req/sec * 512 Kb/req = 15,360 Kb/sec = 15.360 Mb/sec, which
      is less than 100 Mb/sec, so 100 Megabit Ethernet will suffice.
