[OT] SATA/SAS Chip attached to an AT91SAM9RL64 + Drivers?

Hello,

we have the need to attach 2-4 SAS drives (e.g. Seagate  ST373455SS)  to
an (maybe) AT91SAM9RL64 (it has 118 I/O) and while searching to death, I
now ask here, if someone know a manufacturer of  SATA/SAS  µChips  which
can easyly attached?

Speed is no problem, we need only ultra reliable storage and Low-Energy.

Most Chips I have found are PCI based which I definitively can not use.

OR what about USB-SATA µChips?

The AT91SAM9R64 (is cheaper and only 49 I/O) has  a  USB 2.0  High-Speed
controler, if I attach a USB-Hub chip (NXP?) to it and then 2-4 of those
USB/SATA converter?

Then I need to know, where to get those USB/SATA Converter chips!

I should note, that the WHOLE PCB can not be bigger then a 2"5 drive.

Thanks, Greetings and nice Day/Evening
