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.
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.
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.
I would go with ZFS via Truenas. It makes the setup pretty simple and it will have all the benefits of zfs
Torrents are never equally in demand. A large amount of ram could maybe cache the majority of reads, even to a multi-TB array.
