What to do with Plex/Sim Rig/HTPC

[Tweakk]

I have a second system running Windows 10, I use it to host my Plex server, a racing sim rig, and HTPC to stream Netflix/Plex etc. Everything is running off the main m.2 1TB drive, while all of my media is currently stored on x4 4TB NAS HDDs. The motherboard I have only has enough SATA ports for 5 drives, I am stuck at an impasse on what to do and looking for some opinions/recommendations.

 

I have been thinking about doing an internal Raid Controller with SAS, connect 4 more drives and run them in raid. Slight issue with this plan is I need to find a way to store all my data while setting up the Raid array and that is about 12-13TB

 

My second thought is just to get PCIe SATA Expansion card and just continue to run the drives normally like I have been doing.

 

What ever route I end up taking, looking to have something that is gonna require little maintenance and I can just leave it running in the background and use it whenever needed.

 

I would appreciate any advice, recommendations or thoughts on this.

 

Thanks
