5 Reasons 16GB RAM Is Enough for Nextcloud, Plex, and MariaDB

Nextcloud and MariaDB are not memory hogs Unless you are syncing terabytes of files or running dozens of concurrent connections, these services stay well within 16GB.

Plex only needs more RAM during heavy transcoding Multiple 4K transcodes at once will push memory, but for typical home use with a handful of streams, 16GB handles it fine.

Docker containers add minimal overhead Each container uses some memory, but Docker itself is lightweight. For light to moderate use, you will rarely hit swap.

16GB works for a typical home setup with a few users If you are not running a large-scale deployment, 16GB is sufficient for everyday tasks like file syncing, media streaming, and database queries.

The only reason to jump to 32GB is heavy concurrent use If you plan to run many simultaneous 4K transcodes or sync massive file libraries, upgrade. Otherwise, save your money.
