Without answering your specific question, just remember that sata_mv is
considerly "highly experimental" right now, and still needs some
workarounds for hardware errata.

For now, the goal is a system that doesn't crash and doesn't corrupt
data. If its occasionally slow or spits out a few errors, but otherwise
still works, that's pretty darned good :)
