I don’t know, but ideally that data would be cached in RAM. Maybe if you used intelligent tiered storage with a flash tier it could reduce wear and access times.

Ultimately I doubt that this is going to have a significant impact on drive lifespans. A surveillance camera PVR is writing 24/7 which is more intense, and those drives still last plenty long.

Not feesible, unfortunately, if we are talking about multiple terabytes of data.

Could you clarify what you mean?

That’s a fair point; however, I have seen special hard drives exactly for this purpose.

Interestingly enough, there are HDDs purpose made for surveillance (eg. WD Purple), and their special feature is that they’re dumb as bricks: since surveillance more or less continually writes, and only really reads when user directed, there’s practically no start-stop-move head, no predictions, no sleep, no need to cache system files… Just write-write-write in a line, then when you run out of space, start over.
