I collected the results of countless hours of testing where it belongs to: in the community wiki: http://linux-sunxi.org/USB/UAS#OK
As a side note: I would suspect A83T's USB implementation to be the same as H3's so if you would care about your users and keep in mind that linux-sunxi community might get mainline kernel support for A83T working in the future choosing an UASP capable USB-to-SATA bridge would be the best choice since both sequential transfer speeds improve and especially random IO will get faster with mainline kernel.
Again: Why did you choose the slowest USB-to-SATA bridge in the world? There must be a reason why you chose exactly the worst option possible? Do you develop the hardware you sell? Or why can't you tell why you chose inferior components?
