are HD already using this? and is the performance significantly better?
More aboutsata important
yeah there are a couple mechanical hdds using this but its really meant for SSDs grant it the sata 6gbs are far and few just give it by the end of the year there should be more and it will cheapen the sata II which are still fast and faster then a mechanical hdd
so does a SSD that is 6gb compatible like really really fast compared to a SSD 3gb compatible?
