As I am in the process of changing my ryzen system into a diy NAS, I had to deal with the problem of limited ports and specifically that the onboard ASMedia has limited bandwidth.
All the motherboards I have owned that have ASMedia SATA ports use the 1061 controller, this is a 2 port controller that utilises a single lane of PCIE Gen 2, even if the board is a PCI gen 3/4 board. This will be primarily why people get poor speed's on solid state drives.
Well I ordered a 1064 controller, not really found a way to buy these from reputable stores so it was from a chinese supplier, the 1164 is better but the 1064 is still a good improvement over what we get integrated onto boards.
This controller has 4 ports, but also a key change is it is now a PCI gen 3 controller, still single lane, but up a generation of bandwidth, it now should be able to utilise something like high 900s total bandwidth, vs about 400 on the 1061, in practical terms probably nearer to about 900 vs about 350 on the 1061.
Speedtesting on my 850 pro SSD yielded a peak speed of around 540 MB/sec. Which is similar to what a reviewer got on a new unit.

It seems to hold up well up until the 4k tests, now this 850 pro I took out my PS4 pro, it was scorching hot, during its time in there it gained thousands of crc errors, and probably has never had trim ran on it, so I will post back if the scores improve after a secure erase which I might do.
On the default tests it hits 560 read and 532 write, but I adjusted the settings to match the older build of diskmark used in the review.
The plan is to use this controller on direct passthru to a VM hosting the ZFS storage, or at least directly passthru individual drives, the drives will be spindle so in that respect the peak performance doesnt matter, I did the test out of curiosity.
