Try building a test kernel with an added SW-quirk for the ASM1062, like described here:

Just replace the device ID mentioned in the...
Your buzzwords are "S4/suspend_to_disk" for the virtualized OS and "hookscripts" (https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_hookscripts) for the Proxmox side. Have fun!
If you want to compare, then please also try 6.14.x on Proxmox, as it is easily installable as well. It might be, that the power-related behavior somehow changed with the kernel update.
Would you care to elaborate on which kernel version(s) you tried when running Ubuntu?
Also what did you do exactly (in the original Proxmox installation and now in the Ubuntu)? Did you tune the settings (e.g. "powertop --auto-tune"), or just...
You pass-through what you need and leave what you need on the host (!) out of the vfio-pci configuration. Should be as easy as that, basically. That means you define your added Intel A310 with it's PCI-ID for vfio-pci, while you just do nothing...
Für einen reinen Fileserver (zum Beispiel) brauche ich keine Virtualisierung, bzw. der Overhead der dafür anfällt ist völlig unnütz.
Also entweder es gibt irgendeine Anforderung, die Virtualisierung wirklich erfordert, oder man macht sich nochmal...
Die Schnittstelle hat mit der Haltbarkeit erstmal gar nix zu tun.
Auch eMMCs gibt es Industriequalität, die sowas locker abkönnten. Nur logischerweise verbaut Ugreen solche nicht, da das niemand zahlen wollen würde.
Worauf es letztlich ankommt...
Ich hätte da eine Theorie:
Laut deinen bisherigen Beiträgen sind "485.3M" übrig/ungenutzt.
Das enspricht nach Umrechnung so ziemlich genau 473 MiB.
Also (( 485.3M * 1000 ) / 1024).
Und siehe da, das Laufwerk meldet eine Größe von "238.47 GiB"...
This is one of the best examples for showcasing the mindset, that you often see from people coming from the Microsoft (paid-software) realm.
You see some sense of entitlement for a certain function, that one is looking for. And if that function...
For the question of distribution for testing:
Due to the huge number of users, the availablity of a mainline linux kernel repository and the fact, that Proxmox actually uses a adjusted Ubuntu kernel, Ubuntu is what I would choose.
Just use the...
As already mentioned by others, passthrough is by no means a trivial topic.
In addition, you are using a consumer GPU, for a task that usually (besides the home tech enthusiast, homelabber or whatever crowd) only used in a professional setting...
And who exactly is to blame for those "mistakes"? Anyone "explicitly" told you to get that very hardware, because it would work flawlessly out of the box?
Sorry, but assuming something must work is no reason for bitterness, once you realize that...
More details, or otherwise there is no sense in continuing this topic:
What exact kernel version is currently used?
What exact 10G card do you have?
And finally what exact HDDs are you mentioning?
Losing your mind over a few extra Watts is...
