Sorry that I didn't mention it right away, but what is your PCI-E speed when you're trying to go over 221?
I had best results if keep PCI-E speed half of the BCLK.

640. I don't pretend to be an expert on any of this, or to know more than (especially you) any of you here, but I've read every page on the thread below and it is the consensus that the marvell
won't give full performance.
Here's on the intel controller
Here's on a LSI raid card
Here's on the Marvell controller 9128
Hmm... Strange... As you said, there must be something more. I wouldn't be satisfied with the answer: one PCI-E lane is to blame.
If there was any other way to test...
I think I found one: Buy ASRock SATA3 Card for 25-30$ (sorry for saying so directly: go and spend money ). It is PCI-E x1 SATA3 controller with Marvell 88SE9123 / 88SE9120 chipset. Similar chipset, still one lane used, but different aproach.
Maybe you get more conclusive results.
