The Momentus 5400 FDE drive may be integrated into the computer system in the same way you would inte- grate a non-FDE Momentus drive. The encryption key is enabled and operational when the drive leaves the Seagate factory. No user id is required to access the drive, so the data on the drive is accessible to anyone possessing the drive. The drive will encrypt data without a user id.

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 random average of at least 5,000 measurements of seeks between random tracks, less overhead. Typical seek times (msec)* Read Write Track-to-track 1.0 1.5 Average 12.5 14.5

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 10. Typical power measurements are based on an average of drives tested, under nominal conditions, 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

2.9.1.1 Typical current profile Figure 5. Typical 5V startup and operation current profile 2.9.2 Conducted noise Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on the +5 volt line. 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 Volt

2.10 Environmental specifications 2.10.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual drive case temperature should not exceed 65°C (149°F) within the operating ambient conditions. Above 1,000 feet (305 meters), the maximum temperature is derated linearly by 1°C every 1000 feet. Operating 5° to 55°C (41° to 131°F) Nonoperating –40° to 70°C (–40° to 158°F) 2.10.2 Temperature gradient Operating 20°C per hour
