1.5 Seek time
All seek times are measured using a 486 AT computer (or faster) with a
8.3 MHz I/O bus. The measurements are taken with nominal power at
25°C ambient temperature. All times are measured using drive diagnos-
tics. The specifications in the table on page 8 are defined as follows:
•Track-to-track seek time is an average of all possible single-track
seeks in both directions.
•Averageseektimeisatruestatisticalrandomaverageofatleast5,000
measurements of seeks between random tracks, less overhead.
•Full-stroke seek time is one-half the time needed to seek from the first
data cylinder to the maximum data cylinder and back to the first data
cylinder. The full-stroke typical value is determined by averaging 100
full-stroke seeks in both directions.
Medalist 4340, 3230, 2120, 1721 and 1010, Rev. A 7

Seek type Seek (msec, typ.) Read (msec, typ.) Write (msec, typ.)
Track-to-track 2.0 2.5 3.5
Average 12.0 12.5 14.5
Full-stroke 21.5 22.0 23.0
Average latency: 6.67 msec
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.
1.6 Start/stop times
Power-on to Ready (sec) 14 (typical)
Standby to Ready (sec) 10 (typical)
Ready to spindle stop (sec) 8 (typical)
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 before executing a read or write operation.
Servo electronics are active. Seek mode poweris measuredthrough 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,
basedona16-sectorwritefollowedbya32-msecdelay,thena16-sector
read followed by a 32-msec delay.
8 Medalist 4340, 3230, 2120, 1721 and 1010, Rev. A

Operating power and current are measured using 40% random seeks,
40% read/write mode (1 write for each 10 reads), and20% drive inactive.
Idle mode power is measured with the drive up to speed, servo electron-
ics are active, and the heads are left in a random track location.
During Standby mode, the drive accepts commands, but the drive is not
spinning, andtheservoand read/writeelectronicsare inpower-downmode.

1.7.2 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 triangular-wave injected noise at up to 25
MHz.
•Using 5-volt power, the drive is expected to operate with a maximum
of 100 mV peak-to-peak triangular-wave injected noise at up to 25
MHz.
Note. Equivalent resistance is calculated by dividing the nominal volt-
age by the typical RMS read/write current.
1.7.3 Voltage tolerance
Voltage tolerance (including noise): 5V ±5%, 12V ± 10%
1.7.4 Power-management modes
These drives provide programmable power management to provide
greater energy efficiency. In most systems, you can control power
management through the system setup program. These Seagate drives
feature several power-management modes, which are summarized in
the following table and described in more detail below:
Mode Heads Spindle Buffer
Active Moving Rotating Enabled
Idle Moving Rotating Enabled
Standby Parked Stopped Enabled
Sleep Parked Stopped Disabled
Active mode. The drive is in Active mode during the read/write and seek
operations.
Idle mode. The spindle remains up to speed. The buffer remains
enabled, and the drive accepts all commandsand 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 Standby mode automatically after the drive has been
inactiveforaspecifiablelengthoftime. InStandbymode,thebufferremains
Medalist 4340, 3230, 2120, 1721 and 1010, Rev. A 11

enabled, the heads are parked and the spindle is at rest. The drive
accepts all commands and returns to Active mode any time disc access
is necessary.
Sleep mode. The drive enters Sleep mode after receiving a Sleep
Immediate command from the host. The heads are parked and the
spindle is at rest. The drive leaves Sleep mode after it receives a Hard
Reset or Soft Reset command from the host. After receiving the reset,
the drive exits Sleep mode and enters Idle mode with all current emula-
tion and translation parameters intact.
Standbytimer.EachtimethedriveperformsanActivefunction(read,write
or seek), the standby timer is reinitialized and begins counting down from
its specified delay times to zero. If the standby timer reaches zero before any
