I'm seeing quite a few technologies going from a parallel interface to a serial one. Examples: PATA -> SATA, regular SCSI -> SAS, etc. My question is, how can serial be faster? That, for me, goes against logic. I would think parallel would be faster. Kinda like saying trying to increase the number of cars per minute on a road by going from 8 lanes to 1. I've noticed people who read & post to these forums are fairly knowledgeable so can someone explain this to me?
