Well last night my Hikvision NVR was driving my cats nuts with a constant beeping. When I took a look at it the WD Purple drive was dead. Only 15 months old, so packed it up today and sent it off to WD for warranty replacement. This is what I have for a PC, once the WD Drive comes back, I'll put it in here and not in the NVR. This currently has a Samsung Pro 850 SSD 128Gb for C drive and a 1Tb for D drive. I have been running BI on this in eval mode for the past week or two. Got most figured out aside from some phantom emails from car lights glaring off my parked cars in the driveway.
