Jim,
you are absolutely right in general sense, but the title of the post talks about "FAST audio/mid/mgu/sgu/, etc"
I would guesstimate that your 3GB/s controller would perform very close to my 6gb/s or even close to T.bolt 3 as far as BIAB RT generation goes. They guy in the video talked about this. The particular speed is closely related to specific working scenario. BIAB re-generations is that very special scenario smile

No matter how you view this, SSD's are the NOW and near future. So far I am very happy with them. I replaced a couple of "spinners" on my work computers and using one in my music computer. The speeds can not compare to the older hard drives. This video is excellent for someone who is looking to upgrade.

But still, I think PG have to find a way to speed generations up a bit smile
