Inatek KT-4006 (FL1100) confirmed working OOB in El Cap. Great speeds. Can't boot from a disk connected to this card, though.
Also works fine in my version of 10.9.5, so it seems. Nice.
As I posted in that other thread, my Etron EJ168A is working great.
Can you boot from a esata disk connected to the ASMedia 1061 card?
The fact that I can't boot from the Inatek is a serious drawback.
