Very overly simplified:
ATA drives in the beginning were all Parallel ATA. There were no other
options so the parallel was not stated most of the time. Parallel
means 8 data lines working in unison.
Serial ATA (SATA) drives came on the market and there needed to be a
way to distinguish between original ATA drives and the new spec. So
they added the originally implied P(arallel) to the beginning of ATA.
Serial is the 8 data bits going one after the other.
This then is to say all ATA drives are in fact PATA? It seems to me
adding (S) to the original named ATA should have been good enough to
distinguish SATA from the earlier technology?
