Initial NAS for video editing

[Enquiries]

I found you when looking at the Asustor Flashstor 6 FS6706T - 6 Bay All-SSD NAS Storage. I was looking for a NAS that uses SSD, but am happy to hear your thoughts on SSD NAS vs SATA. I am happy to access via usb or Ethernet. My wife and I work from our RV, so small is important. My primary use case is editing up to 4K video and secondary to use as backup for two laptops.
Thanks for any guidance and recommendations you may have.
I appreciated your insights in your YouTube videos.
Best Regards.
