Differences between PATA and SATA hardrive are most visible in regards to the cables. A PATA hard drive has what is called a ribbon cable which is kind of big compared to the small SATA cable. The PATA ribbon cable has 40 pins that connect to the hard drive and/or motherboard whereas the SATA cable only has 7 pins allowing for the computer as a whole to be much cooler due to more empty space inside it for air to flow more freely. Also, I believe that the SATA drives are faster than IDE or PATA, especially if it is a SATA III which can transfer at speeds up to 6 gbs/per second.

Is SATA faster than PATA?

The term PATA was actually created to refer to all the old Parallel drive technoligy, because SATA is supperior. So, the term PATA was created to cover outdated technoligy and none of the technology it covers was called that when it was new. We used PATA as standard since 1994... The original PATA standards transfered data slower than internet connections do today, had a 650MB limit. SATA is light speed compared to PATA a paddle boat.
