Device Overview (3) Current Requirements and Power Dissipation Table 1.3 lists the current and power dissipation. Table 1.3 Current and power dissipation Spin up (*1) Idle R/W (on track) (*2) Seek (*5) Standby Sleep Energy Efficiency (*4) Typical RMS Current MHL Series MHM Series 0.9 A 0.9 A 190 mA 160 mA 520 mA 500 mA 490 mA 460 mA 50 mA 50 mA 20 mA 20 mA - - Typical Power (*3) MHL Series MHM Series 4.5 W 4.5 W 0.95 W 0.8 W 2.6 W 2.5 W 2.45 W 2.3 W 0.25 W 0.25 W 0.1 W 0.1 W 0.032 W/GB 0.040 W/GB (rank E) (rank E / MHM2200AT) 0.040 W/GB (rank E / MHM2150AT) 0.080 W/GB (rank D / MHM2100AT) *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 1-6 C141-E104-03EN
