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
exceed 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.
1.6 Start/stop times
1.7 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 and does not execute a read or write
operation. Servo electronics are active. Seek mode power represents
the worst-case power consumption, using only random seeks with read
or write latency time. This mode is not typical and is provided for worst-
case information.
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.
Operating power and current are measured using 40 percent random
seeks, 40 percent read/write mode (1 write for each 10 reads), and 20
percent drive inactive.
Idle mode power is measured with the drive up to speed, with servo
electronics active, and with the heads in a random track location.
Power-on to Ready (sec) 10 (typical)
Standby to Ready (sec) 10 (typical)
Ready to spindle stop (sec) 12 (typical)
