Fine,
basically the fastest desktop hard disks barely saturate a SATA/150 link. The drive does not have the speed, nor capability to completely over run a 1.5gbps bandwidth rating. Let alone 3gbps. In other words. it is over kill that is unused and can't be used by the drives. In some instances however, this extra potential *can* be used but this is rare, especially for an average-competent user.
It reminds me of AGP vs PCI-E wars of a year or so ago. Yes, PCI-E is a much faster bus and with far greater potential but until recently, with the 7800GTX + cards, this was wasted. In fact, the main advantage with PCI-E was not it's wider bus but it's amount of local power it provides, unlike agp where 4 pin molex plugs must be plugged into the PSU to provide enough power to run the card.
See the western digital raptors? yep, they use/d sata 1.5gbps and were designed for speed and came out well after the 3gbps standard.
