5 Reasons 16GB Is the Sweet Spot for a Home Server

8GB is too tight for real use You can run Plex and a few containers on 8GB, but you will hit swap or out-of-memory kills the moment you transcode a 4K stream or spin up a database container.

16GB gives you breathing room Plex loves RAM for transcoding, and containers silently eat a few hundred MB each. At 16GB, you can run Plex, Pi-hole, Home Assistant, and a database without stress.

The jump from 8 to 16GB is the most cost-effective upgrade You get the biggest performance gain per dollar. 32GB is overkill unless you run VMs or heavy downloaders.

DDR4 is cheap right now If your motherboard supports it, buying 16GB is a no-brainer. Your server will feel snappier and you will avoid mid-movie buffering.

You will avoid late-night troubleshooting Future you will appreciate not having to debug out-of-memory errors at 2 AM.
