Page 18: Seek Time
Seek time Seek measurements are taken with nominal power at 25°C ambient temperature. 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. •... -
Page 19: Power Specifications
Power specifications The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 2 on page 22. 2.7.1 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 and 12.0V input voltage at 25°C ambient temperature. -
Page 20: Conducted Noise
2.7.2 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 square-wave injected noise at up to 10 MHz. -
Page 21: Environmental Specifications
Environmental specifications 2.8.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual drive case temperature should not exceed 69°C (156°F) within the operating ambient conditions. Operating: 0° to 60°C (32° to 140°F) Nonoperating: –40°... -
Page 22: Shock
2.8.5 Shock All shock specifications assume that the drive is mounted securely with the input shock applied at the drive mounting screws. Shock may be applied in the X, Y or Z axis. 2.8.5.1 Operating shock These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 70 Gs based on half-sine shock pulses of 2 msec during read operations. -
Page 23: Acoustics
Seagate follows the ECMA-74 standards for measurement and identification of PDTs. An exception to this process is the use of the absolute threshold of hearing. Seagate uses this threshold curve (originated in ISO 389-7) to discern tone audibility and to compensate for the inaudible components of sound prior to computation of tone ratios according to Annex D of the ECMA-74 standards. -
Page 24: Reliability
EN 55022, Class B and the immunity levels are defined by EN 55024. Drives are tested in representative end-user systems. Although CE-marked Seagate drives comply with the directives when used in the test systems, we cannot guarantee that all systems will comply with the directives. -
Page 25: Fcc Verification
Seagate has tested this device in enclosures as described above to ensure that the total assembly (enclosure, disc drive, motherboard, power supply, etc.) does comply with the limits for a Class B computing device, pursuant to Subpart J, Part 15 of the FCC rules. -
Page 26: Environmental Protection
The silver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide, chlo- ride, and nitrate contaminants. Sulfur is found to be the most damaging. In addition, electronic components should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an ambient relative humidity greater than 95%. -
Page 27: Configuring And Mounting The Drive
Configuring and mounting the drive This section contains the specifications and instructions for configuring and mounting the drive. Handling and static-discharge precautions After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic dis- charge (ESD) hazards. Observe the following standard handling and static-discharge precautions: Caution: •... -
Page 28: Configuring The Drive
Configuring the drive Each drive on the Serial ATA interface connects point-to-point with the Serial ATA host adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point relationship. If two drives are attached on one Serial ATA host adapter, the host operating system views the two devices as if they were both “masters”... -
Page 29: Drive Mounting
Drive mounting You can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the bottom-mounting holes. See Figure 3 for drive mounting dimensions. Follow these important mounting precau- tions when mounting the drive: •... -
