Can I use WD Red Plus 6T/8T on my old NAS (Pro 4) which has been updated to OS6 (6.9.4)
Basing on this: https://kb.netgear.com/20641/ReadyNAS-Hard-Disk-Compatibility-List
4T is the max size.
But I have updated the OS to OS6 (6.9.4). Can I use WD Red Plus 6T/8T ?
Thanks a lot.

But I think it's kind of waste to buy a new 3T disk these days. I plan to buy 2 new 8T disks to replace my THREE 3T disks. Laster I could get more space by adding extra 8T disks. Do you know what's the easiest way to do this without copy all data out? - kamanwuAspirantForget to mention, my 3 old 3T disks are SMR, NOT CMR.
