Well, the whole point is to have it look like a normal SATA drive, even
to the point that you can boot off of it, without having to load a
single driver.
Now, you could offer that you could recreate a SATA controller on the
card, with a SATA bios, etc. And then you could get the increased speed,
and still have bootable functionality.
But it is a version 1.0 of a product, and I'm sure they tried to make it
as cheap as possible (and within their own capabilities.)
