Greetings from across the pond near Albuquerque, New Mexico, USA. Another super-max-groovy video. I particularly liked the part where the video shows your tapping your spoon against a rather strong-looking cup of tea. Don't ask me why, I can't explain it. Maybe it's just showing the contrast between the complex and the simple enjoyment of a cup of tea, like the feeling one gets lounging in a hammock after a particulary long and difficult stretch of Python coding.

Another commentator has raised the question of power consumption. As a NAS is a 24/7 thing, at what point does it become cheaper to use SSDs than recycle spinning rust, even if it's free? Drive transfer speed is not an issue here, as the network is the limiting factor. Could micro SD cards serve as memory for a low-activity NAS?

[@ExplainingComputers]

Yes, OMV can be run off any drive on the system -- here for example the onboard eMMC -- although that drive cannot also be used as a storage volume. Remember this is just a test build to demonstrate RISC-V development, and in no way presented as typical end-user solution. I did an end-user OMV setup on a mini PC here -- kzbin.info/www/bejne/on6ufGp6irt4o7M This all said, running OMV from a (decent) microSD card should present problems with a NAS, as writes will be minimal once the system has loaded into RAM, and using a large card (here I think it was 32 or 64 GB) will provide ample wear levelling capacity.
