HI, I have an old Netgear "ReadyNAS NV+ RND4100 V3" .....that's what it say's on the back of the machine on a Silver sticker. I've read that it isn't really a "V3"  but then I've read a lot of ambiguous information on this machine and I struggle to find clarity. The machine Is metal framed and Silver in colour, bought brand new around 2011. It's currently populated with four 2TB drives Configured In a RAID 5 configuration. I currently have four Seagate 8TB drives available to use. What is the maximum drive size that can be used with this NAS? Will it take the  8TB drives or will I hit 32bit addressing limitations when trying to use 32TB in raw mode or approx 24TB when configured in RAID 5?

Unfortunately, the 32-bit addressing limit doesn't work that way.  If the address space needed for the drive is >32 bits, it rolls over, it doesn't truncate at 32 bits.  And it does so for every drive.  The end result will be an even smaller volume than you have now and a whole lot of wasted drive space.  It's a hardware issue on your NAS, BTW, not just software, so there is no way around it.  The only way you can add space to your NAS is via USB (where you are also limited to 2TB, I believe), but your NAS has notoriously slow USB.
