Would you please be more specific where 8TiB limit is coming from ? according to http://kb.netgear.com/app/answers/detail/a_id/24555 4.2.26 should support 16TiB (and more after factory reset)
The 8TB limit relates to online expansion and it is relative to the capacity when you last did a factory default. So if you started with e.g. a volume of 1.8TB you couldn't expand past 9.8TB. If you started with a volume capacity of e.g. 11TB then the 16TB limit would be encountered before the 8TB online expansion limit.
You can do a factory default with disks in place to get a volume larger than 16TB in capacity. For the 16TB limit to be an issue with a 4-bay NAS you would need e.g. 6TB disks. Or 5TB disks with a single RAID-0 volume (something I certainly would not recommend).
