IMHO use a smaller 500GB NVME solely for the system drive, store nothing else on it. Point all your data to another drive of your choice.
I'd concur with other posters who say keep the 1080i for now at least.
Netgear Orbi might fit what you need.
I have similar to what you are setting up (I think)
Virgin router in the loft office, one of the Orbi attached to that, 4 spare ethernet access points on that one. Second satellite Orbi is two floors down, also has 4 ethernet points.
The RBK50 gives...
Easy to shuck, best to watch a YouTube on the specific drive to see where the hidden clasps are if you want to keep the case intact.
I've shucked about 12 drives and broke at least one clip on each. I'd say most shuckings are partially destructive until you've done a few.
Standard Sata drive...
I've tried loads as well, only recently discovered it's the highest powered that are the most reliable.
Forget the 24W and 36W ones and go full on with 90 watt ones if you intend to use external hard drives Etc.
An 8 port 60W Sabrent and a 90W 16 port Sabrent are my choice USB Hub tools. No...
Only drives that have failed me in 30 years have all been Seagate. 1x2tb and 2x8tb
WD and Toshiba others all work flawlessly.
Only reliable Seagate drives are ones ripped out of Sky Boxes, most with 60K hours plus on them.
