The disk is owned by to PVE host and then given to the container (not a VM) as a mount point. I could use PCIe passthrough, sure, but using a container seems to be the more efficient way.

I meant mega byte (I hope that's correct I always mix them up). I transferred large videos files, both when the file system was zfs or lvm, yet different transfer speeds. The files were between 500mb to 1.5gb in size
I don't think it's the CPU as I am able to reach max speed, just not using ZFS...
Good point. I used fio with different block sizes:
fio --ioengine=libaio --direct=1 --sync=1 --rw=read --bs=4K --numjobs=1 --iodepth=1 --runtime=60 --time_based --name seq_read --filename=/dev/sda
4K = IOPS=41.7k, BW=163MiB/s (171MB/s)
8K = IOPS=31.1k, BW=243MiB/s (254MB/s)
IOPS=13.2k, BW=411MiB/s (431MB/s)
512K = IOPS=809, BW=405MiB/s (424MB/s)
1M = IOPS=454, BW=455MiB/s (477MB/s)
I'm gonna be honest though, I have no idea what to make of these values. Seemingly, the drive is capable of maxing out my network. The CPU shouldn't be the problem, it's a i7 10700.
Tubearchivist works great for me. Downloader, database and player, all in one. Even integration with jellyfin is possible, not sure about plex though.
Ah, thank you for clearing that up, much appreciated!
Excellent, I'll probably do that then. If I think about it, only one container needs write access so I should be good to go. User/permissions will be the same, since it's docker and I have one user for it. Awesome!
Ah, very good to know. Then it makes sense to use this approach. Now I only need to figure out, whether I can give my NAS access drives of other VMs, as I might want to download a copy of that data easily. I guess here might be a problem with permissions and file lock, but I'm not sure. I'll look into this option, thanks!
That makes sense, especially when the drives are equally old. Thanks for explaining it!
I'm curious. Where is the problem with small drives for RAID5? Too many writes for such a small drive?
That sounds very interesting and I'll definetly look into it. Thank you!
Its videos, pictures, music and other data as well. I'll try playing around with compression today, see if disabeling helps at all. The CPU has 8C/16T and the container 2C/4T.
