I got a bunch of the Seagate Exos x18. Greate price/TB and performance. Though they were only the 16TB SATA variant and not the SAS one.
Syncthing on my Kobo and all other devices where I want access to my books.
I recently wrote a script which finds duplicate files and hard links them. I can share it with you, though there are no guarantees of it's safety. There are probably better already established tools out there.
This list gives you an overview of PCIe devices and their compatibility. If I remember correctly there are some hardware bugs in the rk3399 which makes stock linux hiccup on some SATA-Card/Drive combinations, though it's some time ago that I did fiddle with that. In my experience mrfixit2001's kernel is stable in these secenarios.
I recently did expand my storage. I started with one raid5 array with 4 drives. I just added another drive and grew the array, the LUKS container and the filesystem.
Exim and Dovecot. With a clean IP on a VPS and SPF, DKIM and DMARC I haven't really encountered any problems yet. Though I'm only doing it for about 2 years.
I have a cheap Kobo and put KOReader and Syncthing on it.
I couldn't even work if I had aliases in my muscle memory. Imagine ssh'ing to a server and every second command you issue doesn't exist because it's some weird alias you set up for yourself.
I'll stick with the "pure" command and use tab completion.
That's also part of the reason why I don't use some of the fancy new tools like ripgrep and exa.
So what's stopping you from putting your LaTeX files into a git repo and building them into a pdf when needed?
Nouveau is stable and runs, but don't expect the best performance. The official NVIDIA driver is unstable, lacks proper wayland support but has decent performance. I'd go with anything but a NVIDIA GPU.
