Note. These drives are designed to consistently meet the seek times
represented in this manual. Physical seeks, regardless of mode
(such as track-to-track and average) are expected to meet or ex-
ceed the noted values. Due to the manner in which these drives
are formatted, however, benchmark tests that include command
overhead or measure logical seeks may produce results that
vary from these specifications.

Power Specifications
The drive receives DC power (+5V or +12V) through a four-pin standard
drive power connector.
1.7.1
Power consumption
Power requirements for the drives are listed in the table on page 9. Typical
power measurements are based on an average of drives tested under
nominal conditions, using 5.0V input voltage at 25°C ambient temperature.
Spinup power is measured from the time of power-on to the time that the
drive spindle reaches operating speed.
During seek mode, the read/write actuator arm moves toward a specific
position on the disc surface before executing a read or write operation.
Servo electronics are active. Seek mode power is measured through the
drive’s serial port while the drive executes a series of sequential seeks.
Read/Write power and current are measured with the heads on track,
based on a 16-sector write followed by a 32-msec delay, then a 16-sector
read followed by a 32-msec delay.
