Rockpro64 Sata Card kills itself

[AnujDatar]

So, I just tried different OS versions.

1. Armbian Focal, 5.10.35-rockchip  -> avg transfer speeds -> 3-4 MB/s

2. Armbian Buster, 5.10.35-rockchip -> avg transfer speed -> 10 MB/s

3. Armbian Buster, 4.4.y                  -> avg transfer speed -> 14-15 MB/s

4. Ayufan Bionic, 4.4.190                 -> avg transfer speed -> 9-10 MB/s


I get the same speeds on an Toshiba 5400rpm HDD and a Kioxia sata SSD. I pulled my WD Red out for testing cuz I didn't want to accidentally corrupt my data.

And I know I am not saturating my ethernet connection. I tried transferring the same file to both drives at the same time. They transferred at exactly the speeds I mentioned above, both simultaneously. So there's plenty of network bandwidth left over.

iperf shows 950+Mbps if I connect both devices right to the main router. But, I don't typically use that setting. I have a couple of hubs spread over the house with wired ethernet between them (cableing I installed myself). So, not the same as plugging directly into same switch/router. But even with that, the worst case scenario is `837 Mbits/sec`. So that's not the issue.

I have no clue what is going on. Anyone else run into this? What are the best transfer speeds you're getting?
