Maybe you mean AHCI? A typo can make searching very hard...

I think you mean the Linux support of these controllers? In most cases
it's no problem, but be sceptical with very new or less used ones.
In most cases you look at the chipset, not at the SATA controller.

I don't know SATA controllers who need non-free software to operate, but
many SATA RAID controllers need non-free software to check them, and
e.g. send a message when a disk is bad.

When I am not wrong, you can split a SATA port into two ports with
special cables. I have never used them:
I would only use them in special cases, because it's not normal.
