The SSD is supposed to support up to 1,800 MB/s read speeds and 1,100 MB/s write speeds. So at 169MB/s and 158MB/s that does not cut it at all.

I’ll admit it is not fantastic, but it can never be 500MB/sec or higher with a VF2 board because it is a 1x lane PCIe Gen2, that is the theoretical upper limit if there were no overheads at all. So getting 31-34% of the maximum possible theoretical performance while still debugged new hardware is pretty good. First step get it working, second step get it working for more devices, third step don’t break anything and boosting performance.
