2.7 Seek time
Seek measurements are taken with nominal power at 25°C ambient temper-
ature. All times are measured using drive diagnostics. The specifications in
the table below are defined as follows:
• Track-to-track seek time is an average of all possible single-track seeks in
both directions.
• Average seek time is a true statistical random average of at least 5,000
measurements of seeks between random tracks, less overhead.
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. However,
due to the manner in which these drives are formatted, benchmark tests that
include command overhead or measure logical seeks may produce results
that vary from these specifications.
2.8 Start/stop times
2.9 Power specifications
The drive receives DC power (+5V or +12V) through a four-pin standard drive
power connector.
Typical seek times (msec) Read Write
Average 12.5 13.5
Track-to-track 0.3 0.7
Read/write 15.5 16.5
Full stroke 26 28
Power-on to Ready (sec) 6.5 (max)
Standby to Ready (sec) 6.0 (typical)
Ready to spindle stop (sec) 10 (typical)

Barracuda 5400.1 Product Manual, Rev. G 9
2.9.1 Power consumption
Power requirements for the drives are listed in the table on page 10. Typical
power measurements are based on an average of drives tested, under nominal
conditions, using 5.0V and 12.0V input voltage at 25°C ambient temperature.
• Spinup power
Spinup power is measured from the time of power-on to the time that the
drive spindle reaches operating speed.
• Seek mode
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
Read/write power is 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
Operating power is measured using 40 percent random seeks, 40 percent
read/write mode (1 write for each 10 reads) and 20 percent drive idle mode.
• Idle mode power
Idle mode power is measured with the drive up to speed, with servo
electronics active and with the heads in a random track location.
• Standby mode
During Standby mode, the drive accepts commands, but the drive is not
spinning, and the servo and read/write electronics are in power-down mode.

2.9.2 Conducted noise
Input noise ripple is measured at the host system power supply across an
equivalent 80-ohm resistive load on the +12 volt line or an equivalent 15-ohm
resistive load on the +5 volt line.
• Using 12-volt power, the drive is expected to operate with a maximum of 120
mV peak-to-peak square-wave injected noise at up to 10 MHz.
• Using 5-volt power, the drive is expected to operate with a maximum of 100
mV peak-to-peak square-wave injected noise at up to 10 MHz.
Note. Equivalent resistance is calculated by dividing the nominal voltage by
the typical RMS read/write current.
2.9.3 Voltage tolerance
Voltage tolerance (including noise):
2.9.4 Power-management modes
The drive provides programmable power management to provide greater
energy efficiency. In most systems, you can control power management
through the system setup program. The drive features the following power-
management modes:
• Active mode
The drive is in Active mode during the read/write and seek operations.
• Idle mode
The buffer remains enabled, and the drive accepts all commands and returns
to Active mode any time disc access is necessary.
• Standby mode
The drive enters Standby mode when the host sends a Standby Immediate
command. If the host has set the standby timer, the drive can also enter
