If you enjoy pain and are thinking of trying to use an ARM processor directly 
to implement the SATA system  then ,by all means continue ,

 but your best bet is going to be an off the shelf chipset tied into the ARM 
processor.

however heres a couple of links.

Worse than that, the SATA interface is not at all trivial to design.
I am not sure you can even do that in an FPGA.  I believe Xilinx at
one point claimed they had an eval/dev board with SATA, but I remember
reading a post by a disgruntled customer who found it was not really
compatible.

Search for SATA chips and see what you get.  This is a very high speed
serial interface and requires significant board level design as well
as the right chip.  Don't take this lightly or it will be nothing but
trouble.

I want to design a microcontroller-based SATA peripheral.
Does anyone know of any microprocessor/microcontroller that has a SATA
Device port as distinct from a Host port ?
This would make my task easy ...

Thanks.
