Model overview based on user reviews  
The WD Purple Purple hard drive is highly regarded for its reliability and quiet operation, making it an excellent choice for video surveillance systems. Users appreciate its cool performance, even in compact spaces, and its ability to work seamlessly with both older and modern video recorders. While it is not the fastest drive and is not recommended for use as a primary drive in PCs, its large storage capacity and durability make it ideal for use as a secondary storage solution or in environments where consistent performance is crucial. Overall, the WD Purple Purple is a dependable option for those needing a hard drive for surveillance or as a file dump.
Pros

Cons

The perfect solution for video recorders. It's best not to use it on a PC.
9 January 2020 
Quiet, not fast, cool, with a good out-of-the-box surface, works perfectly with dash cams. I have two such drives, one in the dash cam, and one as a dump drive on the PC.
Quiet, relatively inexpensive, with a good platter surface (both drives that I bought had no failures in either access speed or addressing), cold (even in a small recorder case, the temperature, at an ambient of +23 degrees, does not exceed 38 degrees never got up). Large buffer of 128 MB. By the way, it is perfectly recognized by iron, both ancient and modern video recorders.
Slow, it is not suitable for the main disk on a PC, well, it is intended for a video surveillance recorder, as stated on the official website of the manufacturer.

Excellent model

I can't evaluate how it performs when used for its intended purpose. It was not purchased as a dashcam, but as a file dump, as a second hard drive in the computer. It is spacious, quiet, and does not heat up. The only downside is the speed, but reliability and silence are more important to me. It's been working for two years, no bad sectors.
Reliability, silence, does not overheat.
Not fast. Not suitable for installing Windows on a home PC, there are other models for that.
