Worked really well for me, just put in an API key to actual budget and it pulls all the info from simple fin. Only thing that doesn’t pull for me it categories of the transactions so you have to manually set them up in actual but it does allow for rules.
Looks like that NAS was originally sold with up to 40tb capacity so it shouldn’t have any issues with larger drives. Seems like the “my cloud os” is based on Linux so unless WD built in some weird limit, it should work with 20tb drives.
I don’t have an answer here, never had to rebuild an array. You might be able to use clonezilla which can do a block by block copy of disks and then expand the volume in the OS if it supports it. This is just conjecture, I’ve never done it with a raid array.
That looks like a whole bunch of potential for next season!
