Connect QNAP 464/664 via both USB 3.2 and 2.5G Ethernet?

[Enquiries]

I run a Plex server on a M1 Mac Mini w/ storage on a Drobo 5c, connected via USB 3, which I want to replace. I'm considering a QNAP 464 or 664, and looking at upgrading my home network to 2.5G. From what I understand. 2.5 ethernet would be slower than USB 3.

So, I am wondering if I'd be able to connect the 464/664 via USB 3.2 to my Mini (with an a Thunderbolt 3 adapter) to act as a DAS while also having it connected via 2.5 ethernet into my home network for availability to the rest on my network?

I hope this makes sense and I am thinking about this correctly. Your videos have been incredibly helpful.

Thank you!

You could do that with this Thunderbolt NAS/DAS model https://www.qnap.com/en-us/product/ts-453bt3
But 64 series will not allow that.
Either way, you do not need full USB speeds to be able to stream 4K or even 8k videos.
1gBE is fast enough.

I hope this helps.
