My mobo chip set seems to be bottle-necking my speeds and am wondering if there is an easy work around to obtain SATA III speeds. Like a driver download or do I have to buy a card to put in a PCI-e 2.0 x 1 slot? Have run several utilities for read/write speeds and they all agree ( 280/135) and contacting Samsung they tell me my speeds are SATA II. The Samsung Magician says SATA III is available but have no clue as to how to activate it. Any ideas?
