I have one of the 88SE9123 addon cards
My guess is you are being limited by the pcie lane/lanes dedicated to this "onboard" chip.
I'm getting similar speeds as you are with my M4 128
If we think about it, it's kinda sad:
SSD controller -> ssd host controller -> pcie "bridge" chip -> pcie bus -> pcie host controller -> southbridge -> link to cpu/nb ... can vary of course
each step limited by latency, bandwidth, and potentially os/software factors.
Also worth noting, asmedia is a subsidiary of asus. They apparently are very small chips, but the performance is comparable to marvell. I noticed the asmedia product website has mention of SSD controllers. This makes me wonder if they might dive into the SSD game at some point.
