1.1 About the Serial ATA interface The Serial ATA interface provides several advantages over the traditional (parallel) ATA interface. The primary advantages include: • Easy installation and configuration with true plug-and-play connectivity. It is not normally necessary to set any jumpers or other configuration options. • Thinner and more flexible cabling for improved enclosure airflow and ease of installation. • Scalability to higher performance levels. In addition, Serial ATA makes the tran

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 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. Table 2: Typical seek times Seek times (msec) Read Track-to-track

2.9 Power specifications The drive receives DC power (+5V) through a native SATA power 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, 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

2.9.1.1 Typical current profile Figure 1. Typical +5V only 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

2.9.4 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. The drive features the following power-management modes: Table 4: Power management modes Power modes Heads Spindle Buffer Active (operating) Tracking Rotating Full power Idle, performance Tracking Rotating Self refresh—low power Idle, active Floating Rotating Self refresh—low power Idle, low power
