The ultimate guide on serial ATA controller card!!!

SATA is a computer bus interface that has been used to connect the bus adapters to storage devices such as hard disks to increase storage. It brings a huge change in the computer hardware, where it replaced the PATA in all the new embedded applications. All the new systems have been designed using the SATA controller card. In 2000, SATA was introduced to replace the parallel ATA standard. SATA offered high-speed connections when compared to the parallel ATA. SATA component uses a special type of connector to slot into a system, and it also uses a special type of cable or connector to connect this with the motherboard so that the data transfer rate can be increased.

What is the serial ATA controller card?

As the name says, serial ATA stands for the serial interface. The serial ATA technology is the new generation technology that has been designed to replace the older parallel ATA interface technology. That is the reason why a lot of industries are now manufacturing serial ATA interface controller cards.

How does SATA be different from PATA? 

The first generation of SATA comes with a speed of 1.5GB/s. In 2004, the next generation of SATA has even higher speed, and it continues further as the next updates come with higher data transfer speed. PATA is the older interface that has been originally known as IDE (Integrated drive electronics). With time, the PATA interface has been slowly disappearing. Nowadays, most of the optical drives, as well as the machinery, come up with the SATA interface, and soon we will going to witness the end of the PATA interface completely.

Do you know both the SATA and PATA can be there co-exist in a single machine, but the thing is that the machine should have both the SATA as well as the PATA interfaces? The device and drives present in the device should be compatible to use the interface.

The prior difference between both the SATA and PATA is that SATA is faster, more efficient as well as small in size when compared to the parallel ATA. There are certain limitations of PATA, such as signal period, electromagnetic interference, and integrity as well.

Considering the advantages of the SATA, it is currently in use while the parallel ATA has become outdated with time. SATA also supports hot-swapping. PATA is an outdated technology, while SATA is the new and latest technology that is currently in use.

How does it work?

When it comes to computer technology, the speed needs to be faster. To achieve great speed, the interface has gone in completely redesigning. To limit the number of problems and to achieve a great data transfer speed, the serial ATA interface has been designed. In this technology, the data has been transferred over two separate pairs.

Most of the times, many workers need more hard disk space even common people have started to ask for more hard disk space, and that is the time when a serial ATA controller card comes into role.

Features of the SATA controller card:

  • The transfer data rate of SATA is faster. The bit rate is approximately 150MB/s to 600MB/s. This is the biggest advantage of the SATA controller card.
  • The cable size is smaller; therefore, the weight of the overall system gets reduced, and the connector can be connected to the motherboard of the system with ease. The maximum cable length of the serial ATA controller card is 39.6 inches.
  • The external interface has been provided in SATA while in PATA, no external interface is provided.
  • It provides decreased cable size as well as cost.
  • Hot swapping has been supported in the SATA, where it is easy to detect the added and removed devices when the system is in working condition and operating.

Details about the SATA controller card!!!

The fundamental SATA connector has two twisted pairs, 7 pins, and three ground wires. In this controller card, there is the differential transmission with the clock frequencies that varies. The cable size can be up to 39.6 inches long, while when compared to the PATA, the cable size is short. The several versions of the SATA provide the speed of 600 MB/s data rate. Comparing both the SATA and PATA, SATA is a better option providing fast data transfer, reduced size of the cable, and massive 40 pin connector.
