*1 Current at starting spindle motor.
*2 At 30% disk accessing.
*3 Power requirements reflect nominal values for +5V power.
*4 Energy efficiency based on the Law concerning the Rational Use of Energy indicates the value obtained by dividing power consumption by the storage capacity. (Japan only)
*5 The seek average current is specified based on three operations per 100 msec.
(4) Current fluctuation (Typ.) at +5V when power is turned on
