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.

I always try to go for the best and I take my data integrity very seriously which si why I chose this specific model. 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.

Pros: Easy enough to set up. Linked to my Sonos speakers easily. Capacity sufficient for my music collection (2tb). Good value, too early to comment properly on reliability, but no problems at all so far.
Pros: Speed and usability. Serves multiple purposes. Movie streaming, picture repository, file storage. Cloud accessCons: None yet compared to products like wd cloud
Pros: Perfect replacement for my Yale CCTV hard drive that after 10 years kept corrupting and failing. A good likefor like product but with the added bonus of 1TB extra space meaning more recording time.
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.
Pros: Works according to its specificationCons: This is a like-for-like replacement for a drive that failed after four years of use. I would have expected it to last longer.
We have always relied on Western Digital drives and these purpose surveillance grade are the best.
