I'm looking to upgrade my Synology DS920+ with SSDs for cache acceleration, and I'm wondering what the best options are out there. I've heard mixed opinions about consumer-grade SSDs vs. enterprise-grade ones for NAS use. My main concerns are reliability, endurance, and performance.

I'm considering the Samsung 970 EVO Plus, but I'm not sure if it's overkill or if there are better alternatives specifically designed for NAS systems. Has anyone had experience with Synology's own branded SSDs? Are they worth the premium?

Also, I'm curious about capacity - is a 250GB SSD sufficient, or should I aim for 500GB or even 1TB? My NAS is primarily used for file storage, Plex media server, and some light virtualization.

Lastly, any tips on optimizing SSD cache in Synology? I'd love to hear your experiences and recommendations!

Thanks in advance for your insights!
