I will be adding Ryde SD Cards to the shop as soon as we have resolved a software issue that we are struggling with at the moment. No point in us selling cards if you would need to update them in the next week or so.
Can you explain how you clone the cards. I have just done that for my PI4 to replace a 64 Gb Kingston card that was very very slow for a 32 Gb Sandisk. It is not trivial now, even for cards of the same size, as many backup and restore utilities don't work since Raspian started paying attention to the unique ID. (You need to modify the unique ID back to match to the one you copied from or it won't boot). I am sure there is an easier way - perhaps the utility SD Copy now built in? Not all SD cards sold as the same size actually are the same size.
Have a look here https://github.com/billw2/rpi-clone
I use it for my Pi headless stuff to keep various versions that are working before making changes.
rpi-clone looks interesting.
I don't clone the cards for the shop - each one is built from scratch and then checked for transmit capability before posting. That way I can monitor for system and app updates that break things.
