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 conne configuration options.

• Thinner and more flexible cabling for improved enclosure airflow and ease of inst

• Scalability to higher performanc

In addition, Serial ATA makes the transition from parallel ATA easy by prov iding legacy software suppor t. Serial ATA was d

esigned to allow you to install a Serial ATA host adapter and Serial ATA disk drive in your current system and expect all

of your existing applications to work as normal. The Serial ATA interface connects each disk drive in a point-to-p oint configura tion with the Serial ATA host adap ter. There

is no master/slave relationship with Seria l ATA devices like there is with parallel ATA. If two drives ar e 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. This essentially means both drives behave as if they are Device 0 (master) devices.

e levels.

ctivity. It is not necessary to set any jumpers or other

allation.

Note. Th

The Serial ATA host adapter and drive share the function of compatibility with existing host systems and software. The Command and Control Block registers, PIO and DMA data transfers, resets, and interrupts are all emulated.

The Serial ATA host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as the Shadow Register Block. All Serial ATA devices behave like Device 0 devices. For a ddi tio nal inform ation about how Serial ATA emulates parallel ATA, refer to the “Serial ATA International Organization: Serial ATA Revision 2.6”. The specification can be downloaded from www.sata-io.org.

e host adapter may, optionally, emulate a master/slave environment to host software where two devices on separate Serial ATA ports are represented to host software as a Device 0 (master) and Device 1 (slave) accessed at the same set of host bus addr esses. A host adapter that emulates a master/slave environment manages two sets of shadow registers. This is not a typical Serial ATA environment.

The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 1 on page 17.

2.6.1 Power consumption

Power requirements for the drives are listed in the table on page 9. Typical power measurements are based on an averag

e of drives tested, under nominal conditions, using 5.0V and 12.0V input voltage at 25°C ambient temperature.

• Idle mode power

Idle mode power is measured with the drive up to speed, with

tronics are in power-down mode.
