Where to run Jellyfin

[akcapak]

If i have two hardware options where i can run Jellyfin (with Hardware Transcoding) to play my ~5TB media files which are on an external usb disc at the moment, which one should i use?

1- My current miniPC Lenovo m720q (intel i5 8400t + 8gb RAM + 256Gb SSD)

• Pros: i already have Proxmox VE there. I just have to create a new Jellyfin LXC.
  
• Cons: Jellyfin must read those files through the usb port (bad idea?). I have a limited space with my current 5TB external usb drives. So in the future i may have to buy some more external discs. Maybe something like a harddisk docking station like this one: https://amzn.eu/d/dqkhsQM.
  

2- I may buy a Ugreen 2 Bay NAS (intel N100 + 8gb RAM + any NVMe for Jellyfin + any HDD for my media files)

• Pros: I can buy any 8TB or 16TB Disk and i have enough space for the next year. Also everything can be played inside this one device without needing usb.
  
• Cons: NAS + Disks cost quite a bit. And I will have a second device to run, besides my current miniPC.
  

3- Option 2 + move my current Proxmox Installation and every other VM to NAS, besides Jellyfin. Sell miniPC. 

• Pros: 1 Device for all
  
• Cons: ???
  

If you would like to run Jellyfin as fast as possible (for hardware transcoding), which one would you choose? 
Thanks in advance for any tip.
