2.6 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. • 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 <0.8 <1.
2.8 Power specifications The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 4 on page 28. 2.8.1 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. • Spinup power Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed.
2.8.1.1 Typical current profiles Figure 1. Typical 5V startup and operation current profile Figure 2. Typical 12V startup and operation current profile 2.8.2 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.
2.8.4 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.
2.9 Environmental specifications 2.9.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual drive case temperature should not exceed 60°C (140°F) within the operating ambient conditions. Above 1,000 feet (305 meters), the maximum temperature is derated linearly to 112°F (44°C) at 10,000 feet (3,048 meters). Operating: 5° to 55°C (41° to 131°F) Nonoperating: –40° to 70°C (–40° to 158°F) 2.9.
2.9.6 Vibration All vibration specifications assume that the drive is mounted securely with the input vibration applied at the drive mounting screws. Vibration may be applied in the X, Y or Z axis. 2.9.6.1 Operating vibration The maximum vibration levels that the drive may experience while meeting the performance standards specified in this document are specified below. 5–22 Hz 0.25 Gs (Limited displacement) 22–350 Hz 0.50 Gs 350–500 Hz 0.25 Gs 2.9.6.

3.0 Configuring and mounting the drive This section contains the specifications and instructions for configuring and mounting the drive. 3.1 Handling and static-discharge precautions After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards.
3.2 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” on two separate ports. Both drives behave as if they are Device 0 (master) devices.
3.4 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 5 for drive mounting dimensions. Follow these important mounting precautions when mounting the drive: • Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling. • Use only 6-32 UNC mounting screws. • The screws should be inserted no more than 0.150 inch (3.

4.3.1 Identify Device command The Identify Device command (command code ECH) transfers information about the drive to the host following power up. The data is organized as a single 512-byte block of data, whose contents are shown in Table 10 on page 33. All reserved bits or words should be set to zero. Parameters listed with an “x” are drive-specific or vary with the state of the drive. See Section 2.0 on page 3 for default parameter settings.
Word Description Value 60– 61 Total number of user-addressable LBA sectors available (see Section 2.2 for related information) *Note: The maximum value allowed in this field is: 0FFFFFFFh (268,435,455 sectors, 137 Gbytes). Drives with capacities over 137 Gbytes will have 0FFFFFFFh in this field and the actual number of useraddressable LBAs specified in words 100-103. This is required for drives that support the 48-bit addressing feature.
Word Description Value 128 Security status 0001H 129– 159 Seagate-reserved xxxxH 160– 254 ATA-reserved 0000H 255 Integrity word xxA5H Note. Advanced Power Management (APM) is supported. APM is disabled by default but you may enable APM using the SATA set features commands.
Note. See the bit descriptions below for words 63, 88, and 93 of the Identify Drive data. Description (if bit is set to 1) 38 Bit Word 63 0 Multiword DMA mode 0 is supported. 1 Multiword DMA mode 1 is supported. 2 Multiword DMA mode 2 is supported. 8 Multiword DMA mode 0 is currently active. 9 Multiword DMA mode 1 is currently active. 10 Multiword DMA mode 2 is currently active. Bit Word 88 0 Ultra DMA mode 0 is supported. 1 Ultra DMA mode 1 is supported.
4.3.2 Set Features command This command controls the implementation of various features that the drive supports. When the drive receives this command, it sets BSY, checks the contents of the Features register, clears BSY and generates an interrupt. If the value in the register does not represent a feature that the drive supports, the command is aborted. Power-on default has the read look-ahead and write caching features enabled.
4.3.3 S.M.A.R.T. commands S.M.A.R.T. provides near-term failure prediction for disc drives. When S.M.A.R.T. is enabled, the drive monitors predetermined drive attributes that are susceptible to degradation over time. If self-monitoring determines that a failure is likely, S.M.A.R.T. makes a status report available to the host. Not all failures are predictable. S.M.A.R.T. predictability is limited to the attributes the drive can monitor. For more information on S.M.A.R.T.
