Energy efficiency (rank) (*6)
*1
Current is typical rms except for spin up.
*2
Power requirements reflect nominal values for +12V and +5V power.
*3
Idle mode is in effect when the drive is not reading, writing, seeking, or executing any commands. A portion of the R/W circuitry is powered down,
the spindle motor is up to speed and the Drive ready condition exists.
*4
R/W mode is defined as 50% read operations and 50% write operations on a single physical track.
*5
Seek/W/R mode is defined as 33% seek operations, 33% write operations, and 33% read operations.
*6
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)
