Curious why you went with a 512GB SD card for the Prepperdisk, instead of a usb drive? I guess it might make the enclosure bigger, but every RPi thing I have built has been undone by SD card corruption (unless I used the overlay filesystem).

Good question. Cost and ease of use were the primary drivers. It’s a read-heavy / write-light which means we came expect more life than some use cases. Alternatively we went with nvme on the 1TB/LLM model due to its heavier write profile. Making a backup of the SD card is wise though as a backup.

These things shouldn't need writable FS though.
