2.7 Seek time
Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using
drive diagnostics. The specifications 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 rand om average of at least 5, 000 measurements of see ks between
random tracks, less overhead.
*Typical seek times (msec) Read Write
Track-to-track 1.5 2.0
Average 12.0 14.0
Full-stroke 22.0 26.0
Average latency 5.6 5.6
*Measured in performance mode
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.

Time to ready Typical Max
Power-on to Ready (sec) 3.9 8.0
Standby to Ready (sec) 2.6 8.0
Momentus 42 Product Manual, Rev. A 7
2.9 Power specifications
The drive receives DC power (+5V) through the interface connector.
2.9.1 Power consumption
Power requirements for the drives are listed in the table on page 8. 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
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 is measured based on
three random seek operations every 100 msecs. T his mode is not typical.
• Read/write power and current
Read/write power is meas ured with the heads on track, based on thr ee 63 sector read or writ e operations
every 100 msecs.
• Operating power and current
Operating power is mea sure d using 40 percent random s eek s, 40 p erce nt r ead /write mod e (1 wr i te fo r eac h
10 reads) and 20 percent drive idle mode.
• Idle mode power
Idle mode power is measur ed wi th th e driv e up to s pee d, wi th ser vo ele ctron ics act ive and with the heads in
a random track location.
• Standby mode
During Standby mode, the driv e accepts commands, but the dr ive is not spinning, and the ser vo and read/
write electronics are in power-down mode.

Using 5-volt power, the drive is expected to operate with a maxim um of 100 mV peak-to-peak square-wav e
injected noise at up to 10 MHz.
Note. Equiva lent resistance is calcul ated by dividing the nomina l voltage by the typical RMS read/write
current.

2.9.4 Power-management modes
The drive provides programmab le power mana gement to provide grea ter energy efficiency. In most systems,
you can control power management through the system setup program. The drive features the following
power-management modes :
Table 3: Power management modes
Power modes Heads Spindle Buffer
Active (operating) Tracking Rotating Enabled
Idle, performance Tracking Rotating Enabled
Idle, active Floating Rotating Disabled
Idle, low power Parked R otating Disabled
Standby Parked Stopped Disabled
Sleep Parked Stopped Disabled
• Active mode
The drive is in Active mode during the read/write and seek operations.
• Idle mode
The buffer remains en abled, and the drive a ccepts a ll comm ands and re turns to Ac tive 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 dri ve can also enter Stand by mode automaticall y after the drive has be en inactive for a
specifiable length of time. The standby timer delay is established using a Standby or Idle command. In Standby
mode, the drive buffer is enabled, the heads are parked and the spindle i s 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 command from the host. In Sleep mode, the drive buffer
is disabled, the he ads are p arke d and the spind le is at rest. T he dr ive leav es Slee p mo de after it rece ives a
Hard Reset or Soft Reset from the host. After receiving a reset, the drive exits Sleep mode and enters Standby
mode with all current translation parameters intact.
• Idle and Standby timers
Each time the drive perfo rms an Active function (read, wr ite or seek), the standby time r is reinitialized and
begins counting down from its specified delay times to zero. If the standby timer reaches zero before any drive
activity is required, the driv e makes a transi tion to Standb y mode. In both Idle and Standby mode, the d rive
accepts all commands and returns to Active mode when disc access is necessary.

Caution:
• Keep the drive in the ele ctrosta tic d ischar ge (ES D) bag until you ar e read y for i nstalla tion to limi t the d rive’s
exposure to ESD.
• Before handling the drive, put on a gr oun ded wrist st ra p, or grou nd y ours elf frequently by touching the metal
chassis of a computer that is plugged into a grounded outlet. Wear a grounded wrist strap throughout the entire
installation procedure.
• Handle the drive only by its edges or frame.
• The drive is fragile—handle it with care. Do not press down on the drive top cover.
• Always rest the drive on a padded, antistatic surface until you mount it in the computer.
• Do not touch the connector pins or the printed circuit board.
• Do not remove the factory-installed labels from the drive or cover them with additional labels. Removal voids
the warranty. Some factory-installe d labels contain info rm ati on ne ede d t o ser v ice the drive. Other l ab els ar e
used to seal out dirt and contamination.
