Have been using it for about 18 months.  100% up time and no issues, just going in another direction.

 

Instructions mention 2 TB hard drive, but I've had a 3 TB WD Red drive in from Day 1 with no issues.

 

Selling WITHOUT Hard Drive for $400.  Will add HD for another $75.  Will accept Paypal

I thought nvr were supposedly use purple drives.

It came diskless. It is what my original dealer set up. Again base price is without a disk. Add your own if you want to use a purple one.
