Why are surveillance HDs typically cheaper than equivalently sized HDs

post #1 of 2
Thread Starter 
If I sort a particular HD selection by say '3TB" and sort by price. Why are the surveillance branded HDs typically cheaper than others? Is there some sort of drawback to using a surveillance drive as a primary drive? Or is this just really a 'sticker' for all intents and purposes?

I have not seen them cheaper. I would say they may try to tune/optimize each HDD "type/marketing-thingy" to different kind of usage, whether that works or not I do not know but all the difference I can see is probably in the electronics at best if not only in firmware. Sometimes they offer different cache and rotation speeds but even that can be the same between HDDs with these "marketing labels NAS/surveillance/.../".
