Hello,
i want to add 8x20 TB Toshiba HDDS to my Proxmox and run Plex and some other stuff on it.
What is the best idea here? VM or LXC?

What is the best option to has the highest Read and Write IO? Is it possible, 4x2 Stripped in one Pool? I know there is no dataredudancy, but this data is not really important, evertything could be downloaded again. But one thing, if one hdd gets a fault are only 40TB of data gone or the whole Pool?
What else would be a good solution?
 
If you aren't building a pool for redundancy, then I would assume you will loose the entire pool with a bad disk. Keep in mind I only run RAID/ZFS pools on SAN or NAS arrays, so not much experience making pve a storage array in practice..

You may want to try your initial configuration, then run some benchmarks to see the IOPs, and if that seems lacking, try different disk/RAID/pool and compare benchmarks. Sounds like it's just a play lab, so build it how you like, and test, test, test. Hard to say exactly what is ideal, since you don't seem concerned about data retention, just build what works best for you.

The whole pool. How long with it take to download everything again? If you can download 160 TB again in a reasonable time I would like to know the name of your Internet service provider ;)

I would go for a striped mirror (like RAID10). You won't gain write performance, but read performance will be better. You could also speed up metadata access by adding SSDs as special device. If the special device get broken the whole pool will be broken too though so you need to plan carefully. The redundancy of the special device should be the same like on the hdds so if you are not sure don't bother. RAIDZ will resuld in more usable capacity but slow rebuild times and suboptimal read/write performance. Before going in production you could play around with different configurations and benchmarking them with a tool like fio
