That sounds like it would do all I need. I currently have the 3114s'
little sister in there:
pci bus 0x0000 cardnum 0x08 function 0x00: vendor 0x1095 device 0x3112
Silicon Image, Inc. SiI 3112 [SATALink/SATARaid] Serial ATA
Controller
And had not noticed any particular sloth.. but then I've never been
on a seriously tweaked out hard core machine... so it may be really
slow for all I know.
Do you think it would be a problem having a second sata card in a PCI
slot? That would be 8 sata ports in all, since the A-open AK86
motherboard has 2 built in. Or should I swap out the 2prt for the 4
prt. I really only need 2 more prts currently, but would be nice to
have a couple still open for the future.

Well that would solve the `for future use' issue.
What do you mean it takes up a single slot? Don't all pci cards do
that?

Near as I can tell from the A-Open AK86 manual, the pci slots are
spec'ed at 32 bit with 33 Mhz clock speed and throughput rate of 133
MB.
So does that mean the higher speed of AOC-SAT2-MV8 card would not be
available?
I'm not very knowledgeable about the various PCI+* cards available.
Does the contact portion of the AOC-SAT2-MV8 card look quite different
from old style PCI but just doesn't use all the contacts in the female
receptacle? Or does the contact portion look the same as old
style pci.

I'm not sure I follow what you are talking about there. I'm using the
2 prt version of that card, and didn't do any updating or whatever.
It just worked. I do remember fussing a bit getting the drives to show
up, but as I recall (And its been long enough ago that recollections
could be badly skewed) that was a bios setting.
