When I bought my Dahua oem'd Amcrest-branded 4-series NVR, the specs said the largest single drive it could support was 6TB. Recently, Dahua updated the spec for the old model NVR4116-HS on which my NV4116-HS is based, to specify that it supports 10TB drives.
Tonight, I installed a single 12TB drive and its full capacity was properly reported in the NVR. I'm expect a 14TB or 16TB would have worked just as well.
Just sharing in case any one else was considering trying this but want's confirmation that it works. I suppose your mileage may vary from vendor to vendor, but in my experience with PCs, all drive that use the same logical block addressing scheme and block size are interchangeable regardless of total capacity.

The 12TB drive's form factor is slightly shorter and with any luck, will run cooler than the 4TB drive it replaced.
