*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 mode is defined as continuous random seek operations with minimum controller delay.
