When referring to drive capacity, one gigabyte, or GB, equals one billion bytes and one terabyte, or TB, equals one trillion bytes. Your computer’s operating system may use a different
standard of measurement and report a lower capacity. In addition, some of the listed capacity is used for formatting and other functions, and thus will not be available for data storage.
Actual quantities will vary based on various factors, including file size, file format, features and application software. Actual data rates may vary depending on operating environment and

www.seagate.com Introduction

1.1 About the SATA interface

The Serial ATA (SATA) 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 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, SATA makes the transition from parallel ATA easy by providing legacy software support. SATA was designed to
allow users to install a SATA host adapter and SATA disk drive in the current system and expect all of the existing
applications to work as normal.

The SATA interface connects each disk drive in a point-to-point configuration with the SATA host adapter. There is no
master/slave relationship with SATA devices like there is with parallel ATA. If two drives are attached on one SATA 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.

The SATA host adapter and drive share the function of emulating parallel ATA device behavior to provide backward
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 SATA host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as
the Shadow Register Block. All SATA devices behave like Device 0 devices. For additional information about how SATA
emulates parallel ATA, refer to the “Serial ATA International Organization: Serial ATA Revision 3.2”. The specification can be
downloaded from www.sata-io.org.

Note

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

2.2.1 LBA mode

When addressing these drives in LBA mode, all blocks (sectors) are consecutively numbered from 0 to n–1, where n is the
number of guaranteed sectors as defined above.

See Section 4.3.1, "Identify Device command" (words 60-61 and 100-103) for additional information about 48-bit
addressing support of drives with capacities over 137GB.
