I bought a 3.0 card for a rather older pc running win7. Writing data from an std, I'm only getting about 5.5MB. That's 2.0 speeds. I notice my CPU is barely doing anything and there is almost 4GB of ram available. Even tho I bought the 3.0 card is my mother board only capable of allowing x amount of data to pass. Also, if and only if the mother board isn't holding me back is there a way to allocate more CPU to the task in hopes of speeding it up a bit? Thank you in advance.
