Increasing the performance of native SATA to A10/A20 write speeds up to 120 MB/s with 36/45 MB/s, reading performance is about 200 MB/s.
patch is used in kernel 4.19.38 and above.

I tried this, not sure about read performance yet.

Followed this How to Compile Just One Kernel Module to get new patched ahci_sunxi.ko.

works stably on the old kernel 5.4.13, it constantly hangs on new kernels. expected due to disk I/O sata ssd, but recent tests show that this is due to network driver/interface. if you translate it to 100Mbps/Full, hangs do not appear.
