Difference Between SATA and PATA ! Defference

SATA and PATA Difference :

SATA (Serial ATA) and PATA (Parallel ATA) are two interfaces that are utilized to associate with mass storage devices like hard drives and optical drives. SATA is the successor to PATA, which has now turned out to be obsolete. You'd be hard squeezed to find PATA drives in your local PC stores because they presently stock SATA ones.

There are several factors that made SATA far better than PATA and the greatest one is speed. The most extreme speed of PATA is 133MB/s. In examination , the first and slowest version of SATA is capable of achieving a transfer rate of 150MB/s, while the third revision is capable of four times that at 600MB/s. Not every hard drive are capable of exploiting the speed as mechanical drives are moderately moderate. Solid State Drives (SSD) are more ready to utilize SATA as it doesn't have a similar constraint. SATA gives a slight advantage to mechanical hard drives by method for NCQ. This feature rearranges the request of requests so every one of the situations on the platters can be come to with the least amount of passes.

Another feature you get with SATA is the ability to remove or attach drives without shutting the PC down; known as hot pluggable drives. Unlike PATA where the PC needs to recognize the drives on boot, SATA drives are quite like USB drives that can be swapped on the fly. The hot fitting feature additionally opened up SATA for use as an external interface simply like USB. Otherwise called eSATA, it gives significantly higher speeds than USB and is suited for external hard drives and other compact mass storage devices .

Another major difference between the two is the cables that they utilize. PATA utilizes the extremely recognizable wide ribbon while SATA utilizes cables that are a little more than a centimeter wide. PATA cables were a nightmare to oversee and it squares wind current inside the case. The littler cables of SATA make it a breeze to tuck into sides or corners. PATA cables enable two drives to be attached to a similar link by means of a master/slave arrangement. This is somewhat confusing to a few people as jumpers are employed with the goal that the drive knows whether it is a master or a slave. SATA abandons the master/slave arrangement and each link can connect to a solitary drive.


  • 1.SATA is the present standard while PATA is as of now out of date 
  • 2.SATA is substantially quicker than PATA 
  • 3.SATA is outfitted with NCQ while PATA isn't 
  • 4.SATA drives are hot pluggable while PATA drives are most certainly not 
  • 5.SATA gives an external interface while PATA does not 
  • 6.SATA utilizations smaller cables than PATA 
  • 7.PATA utilizations a slave/master arrangement while SATA does not
