I have a lottttt of data so I got this. I did not realize the transfer rates on 3.5inch spinning drives have gone up. With a USB 3 adapter/reader dock this was transferring over 100mbps. It makes the spinning drive sounds that these make, but it is actually quit quiet. I use it exposed versus enclosed so it is a little more clicky sounding, but sound wise, if it were enclosed, it would probably be unnoticeable. Plus, it doesn't sound that bad - I actually miss the sound of data moving around haha. I would need it to be used for years to really write on reliability as I have neevr owned these, but looking at the specs, this appears to be a similar design, if not the same drive as their commercial grade drives for business. I always try to go for the best and I take ... MoreI have a lottttt of data so I got this. I did not realize the transfer rates on 3.5inch spinning drives have gone up.

The specs that relate to reliability were the highest I could find at a reasonable price point so I am not disappointed. It actually stays quite cool as I transferred multiple terabytes worth of data at a time and it never really got hot, just warm - and this was in an open dock without a fan or active cooling. When I need to access data or write, it is very quick and never gives me trouble. I am pretty sure I will have this for years - especailly as I always get an overkill for my needs to ensure reliability and longevity.

I bought this drive to increase the capacity of my security DVR from 2TB to 12TB. I have had good experience in the past with various types of Western Digital drives -- no failures at all on drives I purchased new -- and the specifications are good. I was particularly attracted by the five-year warranty. It installs like any other drive, and I don't notice any excessive noise, though there are other noisemakers in the room so I don't have a very good read on this. I did a full surface scan, run by the DVR, which showed no bad sectors. It's a big drive, so it took 36 hours! Overall I am pleased with the drive.
The drives are great and quck shipping. I have about 10 dives of this type I use for cameras and backup system.
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.
These drives are pretty good, no problems almost a year old now. Would purchase again.
WD 10Tb HDD is a good economical solution for a recorder in a residential surveillance system.
Great HDD compatibility with Unifi UNVR. It is a go
We have always relied on Western Digital drives and these purpose surveillance grade are the best.
