Well, first off I stopped watching TV a few years back as there isn’t anything I want to watch on it so I couldn’t possibly believe any advertising. 
The reason I posted the question here is I believed there would be members who could definitively state if a purple drive could corrupt data if used in a desktop PC setup and tell us why that is. Because I see some videos and threads in other sites about alleged data corruption and yet provide no explanation. If I just believed that statement at face value, then I would be no different from the people who believed all the aforementioned stuff on TV. 
You stated that the purple drive was constantly working on the video, but this operation is because it is simulating a DVR setup with 16 cameras simultaneously recording and playing back at the same time. Anyone with basic knowledge of hard drives knows that when an HDD is reading or writing, it is working. A DVR is running 24/7 so the HDD will always work as the recording and playback is continuous. In contrast, a desktop PC isn’t always writing to or reading from the HDD and so if you’re not using it, then the HDD can stop moving (especially when you set up a power saving mode on your system). Obviously if the Purple drive isn’t connected to a DVR but a PC then logically the movement would be like the drive on the left. Same goes if you connect a desktop PC to a DVR (which existed even before there were Purple HDDs), the movement of the desktop HDD heads would be more like the Purple.
So the Purple drive is not optimized for desktop PC use, that’s already established. The Purple drive will not perform as well as a desktop PC in a desktop environment, that’s also clear. My question is, to be very specific and which will ultimately dictate whether to use it in a desktop PC setup is “Will using the Purple HDD in a desktop corrupt data and whether yes or no, why?”
