I can shed some light on that. After the thread was closed I contacted support, and after going through several steps (including applying a thermal pad) they determined the card was defective and told me to buy a new one.
more than half of the advice you received here is more expensive than a 2-bay nas + 2x8TB drives. if you then install tailscale you can connect to it from everywhere and you’d be only bound to the limits of your connection. plus of course you get redundancy and a lot of other usefull stuff.
fyi: the reason why i moved to this solution is that i had a 2TB usb hard drive which broke and i lost all the data.
Only if you actually need the double capacity, you pay for with them being orders of magnitude slower and less portable. It’s all tradeofs.
If partition on a 2tb drive works, that is a no brainier and by far the best solution available imo.
If there are actually 2tb dedicated to the secondary required I’d much rather go with the shittiest dramless 4tb drive I can find (there are sub 200$ ones) than move back to HDDs.
If you actually have any other use for the nas, getting a nas in general would be the way to go if you can live with only having acces to your 2tb of files when you have internet and only at your upload speed.
Buying 4tb hdds these days really isn’t worth it, especially since that size segment is still littered with unmarked smr drives.
But anyway the actual best solution highly depends on use case and that really was not explained so all we can do is provide options.
