There's a couple things to be aware of:
1) You need to make sure that the USB-SATA adapter, whether it is in the cable or the enclosure, supports Linux. Many of them do not. Neither one you linked has any indication of being supported on Linux, so there is a fair chance that it does not. My recommendation would be to find one that uses the JMS578 chip (use "JMS578" in your search terms).
2) RAID is not a backup. There's a distinction to be made here. Are you looking for maximum availability (data will always be accessible), or maximum data safety (least chance of losing data)? These are not the same thing, and often achieving one means taking compromises on the other. RAID will give you availability of data, but it's not so good at keeping the data safe. RAID controllers (especially cheap ones like you'll find in those two devices you're debating) often have a tendency to break and corrupt all the drives.
My recommendation would be to just use the Rock64 (with a high quality 3A or 4A power supply -- no need for the big ones you have in mind) with a JMS578 adapter hooked up to just one SSD, and use the other SSD as an offline backup (connect with a similar adapter on one of the USB2 ports when you want to backup). This will be safer than cheap RAID and there is less to go wrong.
