The SMR does make sense for surveillance, because it is a constant stream layed down, it is not random write access changing a block in files of various places. This show has talked about their usage. The tolerance on dropping bits to keep going with the stream would worry me in data sensitive applications

There are spec sheets, but I have tested myself, brand new Purple Drive out of package and run disk bench marking read/write testing. Writing was steady, read rate was under performing compared to Blacks or Reds.
Surveillance video is not verbatim sensitive, it's better to get the video on there with bits missing than not at all.
Isn't it more like those are overperformers?
LOL. I mean depends on the baseline number, so yeah, you would be correct. But the concern would be as you mentioned the Purple drives don't care (as much) about data loss. Fine for video if you lose a pixel, but bad for mission critical data.
