I’d recommend a single, high-storage SSD. I’m running 1TB on my Umbrel, with Bitcoin Core taking up 630GB, which leaves plenty of space for other apps/data, but you might want more.

Looks a little intensive running blocks data from a different HDD →

I had to remove 3 original partitions, create 1 whole partition, format that partition, and then **install new Ubuntu with 4 partitions**. LVM forced me to use a whole disk so I gave up using them, and just installed Ubuntu without LVM.
