⚠️ Cons & Limitations

❗ CPU & RAM are modest: Only suitable for light workloads; not ideal for heavy Docker use or many concurrent apps.
❗ Gigabit networking limits throughput to ~110 MB/s.
❗ RAM isn’t upgradable, which restricts advanced services and containers.
❗ Some users report software/OS issues or stability quirks in community forums (varying experiences).

What It’s Good For

• Central file storage & backups for multiple computers.

• Home media streaming to TVs, consoles, and mobile devices.

• Basic RAID protection with flexible TRAID and snapshot options via Btrfs.

What It’s Not Great For

• High‑performance NAS apps like heavy Docker containers, large Plex transcoding duties, or virtualization.

• Gigabit‑limited networks — you won’t exceed ~110 MB/s max due to the network interface.
