Moving Plex/Metadata to external SSD

Server Version#: 4.47.3
Player Version#:

Hello, I am using a Synology DS918+ with 4 HDDs.
I am wondering if I could buy a SSD and connect it vio SATA to USB 3.0 Cable to my NAS and run Plex on it.
Is it possible to just move the metadata? Who has experiences with that and some good advice?

Plan is to make the server more reactive/faster Thumbnail-loading.

Greetings.

Synology does not permit it.

It will see the SSD and only allow it to be used as a SSD Cache.

That having been said, PMS cached by an SSD is a lot faster than without.

ok… so how do I use it as cash then? Just plug the ssd in and thats it?
This sounds like a suggestion to buy a ssd anyways?

I’m not suggesting or endorsing it. SSDs have a limited life so will need to be replaced sooner than hard drives. keep that in mind.

When you plug in the SSD and startup DSM, it will walk you through the process of making it a Cache volume.

Link to a Blog over on Synology discussing it and its pros and cons:

Disks are slow but large and cheap, SSD is fast and smaller and more expensive (relatively). Making an SSD cache on your Synology helps offset some of the speed issues with magnetic spinning disk’s for all your access usage.

I defer to ChuckPA on statement that Plex on Synology doesn’t allow it.

Plex has no involvement with the SSD layer.

The package doesn’t care. DSM abstracts the hardware just enough that I can’t see what’s underneath.

Think of the layering as:

  1. The Plex app
  2. – optional SSD cache which is invisible to all applications —
  3. The actuall HDDs which provide the perm and large bulk storage.

QNAP actually allows us to create real SSD volumes. I have 4 SSD volumes in my QNAP and then have the main HDD volume for the movies.
