Certainly, Leo, thank you for considering the ASUSTOR AS6702T 2nd Gen NAS for your Plex Server needs. You have some great options for storage configurations. You can indeed use only 4 M.2 NVMe drives if you prefer, and this setup can make your NAS quite silent. Alternatively, some users opt to use SATA SSDs in the HDD bays, which can help with drive replacement and redundancy. The AS6702T supports both the latest SATA HDD/SSDs and older drives, so you have the flexibility to use various drives depending on your needs. This NAS should work great for your Plex Server at home, and we're here to help if you have any further questions. If you need more information, you can find details on the ASUSTOR AS6702T 2nd Gen NAS on our website.
