Duo V2, Drive Capacity Cap?

documentation seems to suggest a 4tb cap, this is probably more due to technology available at time of print rather than capability of the nas itself

Their datasheets use the biggest compatible drives available at the time of publication, and they don't go back and update them later.

There are limits to volume size in the old ReadyNAS, but you won't hit them with 10-TB RAID-1.

One poster did successfully use 2x10TB in their v2 - https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/Tutorial-10TB-drives-installed-in-Readynas-duo-v2/m-p/1744735

• Seagate Iron wolf (ST10000VN0008)
• WD Red + (WD101EFBX)
• WD Red Pro (WD102KFBX)
• N300 (HDWG11AUZSVA)

The WD102KFBX is enterprise class, and has the longest warranty (5 years; the others are 3 years). 

Though normally I think enterprise class is overkill for a Duo, it's actually the cheapest at the moment (current US Amazon prices are about $60 less than the Ironwolf and the Red+).
