Which hdd ( hard disk drive) SATA OR PATA is of latest technology ?
Normally, parallel devices are supposed to transfer data faster than series devices. For once, this is not true! SATA is actually a lot faster than PATA. A comparison of the cable lengths of the two devices reveals that while PATA cables which number up to 26 can attain a combined maximum length of 18 inches, SATA can have only 1 meter of cable in length. Owing to the abundant number of wide cables for PATA, it is bound to take a lot of space. In an already congested computer cabinet, this makes it difficult for heat, to get dissipated. Compared to that, SATA has only 2 quite narrow wires which are longer in length. This makes it easy to arrange them in a convenient fashion so as to avoid congestion. The most important difference between the two is the data transfer rates they offer. Here SATA is inherently superior. It offers a speed of 600 MB/sec which causes a phenomenal decrease in data transfer time from the hard disk and other devices. However, PATA offers only a paltry speed of
