On sale is this more high end TerraMaster NAS and cheaper than it's previously been. It features an Intel Celeron J3455 quad-core CPU, 10GbE LAN, dual 1GbE LAN, 4GB RAM (Upgrade to 12GB) and 2 USB 3.0 ports on the rear.
An excellent choice for file storage, backups, media playback (e.g. Plex), Docker and even your homelab setup if you happen to have a 10GbE network. Please refer to this document to see what it can transcode in Plex.
Recently TerraMaster released TOS 5.0 which is a whole new operating system different to TOS 4.0 with a lot more features, cleaner UI, more apps and overall runs more smoothly. With TOS 5.0 I use the new Surveillance Manager to record my camera footage straight to the NAS and the new CloudSync app for syncing my OneDrive and Google Drive to the NAS as a backup.
Alternatively you can 'unofficially' install Operating Systems like TrueNAS or even Synology DSM to experience all the apps and features that they provide.
How is this direct quad-bay model upgrade?
