General Overview Serial ATA (Advanced Technology
Attachment) is a computer bus technology primarily designed for transfer of data to and from a hard disk

Physical Structure
A+ = Transmit pin-1 B+ = Receive pin-1
A- = Transmit pin-2 B- = Receive pin-2

Need and Benefits of SATA
Increased data transfer rate ,
Supporting 1.5 Gbps date rate
Easy cable management and cable
length
Increased airflow
Size of SATA connector is smaller than
PATA cables

Differences between PATA & SATA
Up to 133 Mbytes/sec Up to 1.5 Gbits/sec
Tiny jumpers No master/slave, point to point
Eighteen-inch cable Up to 39-inch (1 -meter) cable
Two-inch-wide ribbon cable Thin cable (1/4-inch)
80 conductor 7-wire differential (noise canceling)
40 pin and socket Blade and beam connector (snap in)
Two-inch-wide data connector 1/2-inch-wide data connector
High 5V tolerance for legacy drives Low voltage (.25V) tolerance
CRC on data only CRC on data, command, status
Parallel ATA Serial ATA

E-SATA Initially SATA was designed as an internal
interface technology, bringing improved performance and new
features to internal PC or consumer storage .Creative designers
quickly realized the innovative interface could reliably be
expanded outside the PC, bringing the same performance and
features to external storage needs instead of relying on USB or
1394interfaces called external SATA or eSATA,

LIMITATIONS OF SATA
Drivers and support There are only a few small disadvantages of SATA over PATA. One disadvantage is that SATA hard drives will sometimes require a specific driver to be loaded to a computer when installing an operating system, in order for the computer to utilize the SATA hard drive

SATA II & SATA III SATA-II.which is an extension to the
original SATA standard is seen as the bridging technology from a desktop-oriented SATA to a server-level storage interface, making it a viable, low-cost storage solution for server, NAS and SAN applications.
SATA III, is the next set of specifications following the original SATA and SATAI II storage interface specifications. SATA III doubles the maximum data transfer rate for previous Serial ATA storage interface specifications from 3 to 6 Gigabits per second (6 Gb/s), enabling faster data transfer speeds between storage units, hard drives, optical drives and protocol host bus adapters(HBAs).

Future Scope
SATA-IO plans to make a 6.0 Gb/s standard. Although the theoretical throughput would be doubled, conventional hard disks cannot approach saturating this speed. The 6.0Gb/s standard will however be useful in combination with port multipliers, which allow multiple drives to be connected to one Serial ATA port, as well as with solid-state drives such as RAM disk.
