I was fortunate to have a Database Basics course in the university that was 80% database schema design and 20% SQL queries and indexes. Reasoning for such a split was that fixing a bad database schema is much harder than fixing bad queries.
I bought Sony Xperia 1 V to replace it. It has a 3.5mm headphone jack and a MicroSD card slot. The build quality is excellent but I'm a bit worried what the software support will look like in a few years.
Estonias first SysCon was turned on this summer https://news.err.ee/1608976037/elering-launches-estonia-s-fi...
https://www.armbian.com/ is also pretty awesome and also supports bunch of other RaspberryPi clones for cheaper price.
BTRFS is not that scary. Quota and RAID56 is broken but other features have been stable quite some time. Btrfs is used by default for few Linux distros and Facebook makes quite heavy use of it on their servers https://lwn.net/Articles/824855/
I have been running btrfs on all of my machines since 2016 as transparrent file compression helps a lot with keeping disk usage down.
Btrfs RAID1 even saved my data once when one of the SSD's decided to die suddenly.
For maximum performance you should run databases on top of XFS anyway. It also supports per-file COW via reflinks.
