You don't necessarily need a raid controller, I think a pcie bridge or switch chip will work too. They're still expensive but they're significantly less than $500.
I routinely do 1-4TB images of SSDs before making major changes to the disk. Run fstrim on all partitions and pipe dd output through zstd before writing to disk and they shrink to actually used size or a bit smaller. Largest ever backup was probably ~20T cloned from one array to another over 40/56GbE, the deltas after that were tiny by comparison.
Cold War 1 never ended, the west got a kick out of telling everyone that they won and took their eye off the ball while Russia continued playing.
There are more Russian agents in the US now than ever before and I guarantee that Europe is getting the same treatment. Small amounts of spending can yield outsized results for Russia, they learned this 50+y ago and are continuing to act on it.
Because you're relying on compatibility between older Debian software (systemd, etc) and newer versions installed in the chroot. Things get weird quickly.
Consider a nested privileged container instead (LXC or similar) and cross your fingers that Debian systemd and Arch systemd play nice.
If the above fails just make a VM and pass through the GPU with GVT-g (otherwise pass through the entire GPU.)
If all of that fails install Arch to a USB attached SSD or something.
If you're using an Intel chip look into GVT-g and consider running Arch from a VM, that'll be the closest thing to native.
The unfortunate thing about running an Arch container from a Debian host is that you're relying on an older kernel and an older systemd host side and I've found that often causes compatibility problems inside the Arch container. If you are very, very lucky Arch will just work inside the container, but IME that's fairly rare as systemd often has breaking changes over several releases (and Arch tends to be at least several releases ahead of Debian.)
Congress should be enrolled in the base tier Medicare program and barred from buying any private insurance on top. Health insurance reform would follow within 6mo.
99% of breakages on a rolling release distro are solved by downgrading the broken package until a fix lands so it's not much worse than windows. You want to be chasing recent releases of pretty much everything if you want the best performance for gaming. You could run Debian but you'll be waiting 18mo for any new performance improvements to land.
Install the ProtonPlus flatpak if you need custom proton versions for some games, I usually just add the latest proton-ge and don't have to bother with anything else
Fedora, Arch, EndeavourOS, Nobara and Bazzite are all pretty good bases for a gaming setup. They all have their pain points so I'd boot a couple and see how you like them before making a decision.
I always hate these questions (is X worth it?) because you're asking the Internet to give you an answer to a subjective question. If you want to sort out the answer for yourself it comes down to how much money you can afford to spend on entertainment and whether you think £1 of that amount for a song is worth it.
If you're rich and £1 doesn't matter in slightest and you like the song then it's "worth it." If you're poor and you have £20/wk to spend entertaining yourself then maybe not. Anyway who knows, if you think the song is worth the price then go for it.
Also, just to throw this out there, there are an awful lot of ways to listen to music on the Internet that won't cost you anything. You could always use one of those then later go back and buy music that's particularly meaningful to you. Remember that streaming music pays the actual artists almost nothing, go buy physical media (or better yet go to one of their shows and buy merch) if you want your favorite artists to actually see any money.
Many US food companies won't ship delicate foods during the hot parts of the year. I have a bunch of my staple groceries shipped to me (go food deserts!) and I can't get chocolate or other heat sensitive products from them between late May and mid September.
On top of that just pumping support money into real estate doesn't fix either of the core problems: people aren't being paid enough to afford homes and we're not building enough homes to keep prices reasonable. The end result of this is that home prices inflate even further. If we treated houses as housing rather than investment vehicles we could actually do something about our housing crisis.
