There is no want for a grasp or slave distinction with SATA drives as a result of they every connect with the motherboard with their very own SATA cable. Two IDE/PATA drives, on the different hand, might share the similar knowledge cable, however solely one might use it at a time and thus every required a definite identify. In truth, by the time ATA-2 was permitted in 1996, the spec referred to the drives as machine 0 and machine 1, regardless of grasp/slave being extra generally acknowledged.
When putting in two PATA drives, jumpers on the again of the drives allow you to designate them a grasp or slave, the former of which had no precedence over the latter and motherboards might additionally sometimes boot off both drive based mostly on person choice. “Cable Select” was additionally a jumper possibility that might be chosen on the again of each drives to allow them to mechanically set themselves as grasp or slave based mostly on their place on the knowledge cable.
Serial ATA (SATA) was launched in 2003 and introduced many enhancements together with smaller, cheaper cables, native hot-swapping, and quicker knowledge charges. Within 5 years of changing PATA, SATA represented 99% of the desktop PC market share.
While SATA was the commonplace for a few years, finally it created a bottleneck for quicker storage. PCI Express gives a quicker interface pace than SATA and it is slowly changing it as the new commonplace for prime efficiency SSDs. PCIe utilizing NVMe based mostly storage gives 2-3x the efficiency of an everyday SSD on the SATA interface.
