AHCI Reminder To Self

Just redid a Lenovo SL410 and the HD speed was hopeless. Lenovo doesn't list the SATA AHCI controller with its regular drivers so I didn't think of it. Why did they make me hunt it down?

OMG what is happening?

Oh yea, the AHCI controller

And disabling Windows write cache helps a bit maybe. I thought burst would go up but didn't.
