You need to make sure that you get SATA/USB3 bridges that have no quirks/bugfixes already enabled in the Linux kernel, otherwise UAS or other features might be disabled. Armbian and others did some tests and generally the JMS576/JMS578 seem to work well. Is this with BSP or mainline kernel? You could also file an issue with your description against Rockchip's kernel on github if it is a BSP based image...
