Reliable drives for for critical applications.

I purchased two 18Tb WD Purple Pro drives for a Ubiquiti NVR that I set up at a construction site. I have used these drives before with other UniFi NVRs and they work very well. I just added several additional 4K cameras so I am also adding two more drives to the system. We are using the drives for security and to document the build. I have had other WD Purple Pro drives in use for over a year on similar projects and they have been working well.

Bought 6, one dead on arrival

Bought 6 from different vendors, with Walmart (Jet) being the latest manufacturing date (December 2024). This one from Walmart was DOA. Not Walmart's fault, probably just a bad batch. I also bought two from Walmart that were sold by Newegg and those two were perfect. Overall the drives are great and not too noisy, but this was the first time I received a Western Digital that was DOA. That said, I'll still buy them over Seagate.
