The hptrr(4) driver relies on SCSI CAM/da(4), and does not use the
ata(4) driver in any way.

Re: SATAII: if the product data sheet or the user manual states the card
supports SATA300, then yes.
Re: NCQ: the user manual probably answers this question, or a FAQ/KB
article. I hope you're not planning on disabling write caching on your
disks (as people often ask if controllers or drives supports command
queueing so they can do this. NCQ does not provide the amount of
performance increase like SCSI command queuing does. On the other
hand, TCQ (often found on SAS drives) does.)

I have no idea. I suppose it would have to support pass(4), or provide
the functionality itself (Areca controllers do the latter).

I recommend avoiding Adaptec. I will repeat that: avoid Adaptec.
You are not going to find a SATA card that has non-RAID capability with
that amount of ports. Besides, it shouldn't matter to you if the card
has RAID capability, because nothing forces you to use it. All that
should matter to you is the following:
* Is the card version/model supported under FreeBSD?
* Does the card supports disks in a JBOD fashion (not part of an array)?
* Can I get SMART stats from the drive (or via CLI; see below)?
* Is there a native FreeBSD CLI binary for controlling features of the
controller if I need it?

But neither of these are FreeBSD problems. The same would apply if you
were using any operating system.

I have not seen these on any of our systems. Chances are they're ACPI
or AML errors which can be fixed by the vendor with a BIOS upgrade.
I would recommend asking about this on freebsd-acpi instead.
