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.)
