Serial ata backwards compatible

Unfortunately it took some time for these alternatives to offer the combination of low cost to relative performance that was the key to the success of the traditional PATA interface. They were also completely new interfaces, offering no direct backward compatibility for existing devices. SATA was conceived as the answer. The standard for SATA, when compared with PATA, offers lower signaling voltages and reduced pin count, is faster and more robust, and has a much smaller cable.

This is achieved either using chip sets that support PATA devices in conjunction with discrete components that support SATA devices, or by the use of serial and parallel dongles, which adapt parallel devices to a serial controller or adapt serial devices to a parallel controller. This backward compatibility was not necessarily maintained, however, as over time more motherboards were developed offering SATA interfaces that do not accept PATA devices, particularly hard drives.

However, this mirrored the steadily increasing outmoding of PATA hard drives on the market. Hard disk drives, cables, enclosures, and controller vendors have been supplying Serial ATA products to the industry since It is expected that additional product areas, such as optical disk drives e. Serial ATA technology provides a new serial interconnect designed to change the way vendors develop storage systems.

The first deployments, where price is an important issue, were intended for client applications, entry-level servers and network-attached storage. As the infrastructure continues to develop, Serial ATA will continue to penetrate into higher-end servers and more complex storage systems.

Serial ATA initially defined a roadmap starting at 1. This roadmap supports up to 10 years of storage evolution, based on historical trends. One of the primary requirements of the Serial ATA 1. Because of the legacy support inherent in the specification, operating support will be simplified.

The Serial ATA specification allows for additional features to be added to applications. Additional features will be subject to normal driver validation processes. Understanding how the SATA interface works with SSDs and modules and the specifications of the different versions will help you make the right storage choices for your applications.

Here are a few facts about SATA to help guide you towards the best options. This data rate allows SATA to transmit and receive data much faster than its predecessor. This allows the command set to have backwards compatibility. Revision 3. However, there will be loss of sequential read and write speed rates when a newer SATA interface is hooked up to an older port version.
