Parallel ATA (Parallel Advanced Technology Attachment) is an older kind of computer connection used to attach data storage devices such as hard drives or Solid-state drives to the motherboard. Parallel ATA was previously referred to as Integrated Drive Electronics; It has been almost completely replaced by Serial ATA (SATA).[1]
Advantages
Parallel ATA was developed and released first (in 1986), it was installed in many computers. Its only lasting advantage to speak of is that it uses less power that its successor, SATA.
Disadvantages
Compared to Serial ATA, Parallel ATA offers significantly slower transfer speeds. At first, PATA offered a bandwidth of 16MB/s. Throughout the various versions which came after, the speeds progressed to 33, 66, 100 and finally 133 MB/s. When SATA was released in 2002, it offered a net bandwidth of 150MB/s. It was then upgraded to 300MB/s. Also, PATA cords could not be made as long, since the signals did not carry as well over distance. Lastly, IDE/PATA cables where much wider than SATA. This made it more likely that the PATA cables would inhibit airflow in the computer.[2]
