NETGEAR ReadyNAS NV+ v1 vs NV+ v2 and the 2TB vs 3TB HDD divide

ReadyNAS NV+ on the 2TB or 3TB HDD

Problem Statement: why does my ReadyNAS NV+ v1 only recognize 750GB out of each of the 3TB disks that I’ve installed?

ReadyNAS NV+ (v1) recognizing 746GB of 3000GB WD30EZRX

Answer: Minor versions matter …

tl;dr => (max) 2TB for the v1; 3TB for the v2
