Wouldn't HDD mining destroy the HDD in a matter of days, which would make returns from this kind of investment minimal? I don't even know what this would do to SSDs.
I think mining with an ssd isn't profitable but with mining with an HDD I have the same question in my mind. How long can an HDD live when it's 24/7 working?
while burst mining for over a year the only drive i have killed was 15+ years old and already had bad sectors.
the amount of wear on a drive from reading 1/4096 of plotted space about every 4 minutes is minimal, optimized plots minimize drive seeks (moving the heads) which helps. destroying drives is best done by thrashing them with a lot of writes, reads and seeks (using them for swap space in a machine with little ram is great for this).
as far as ssds, well rewards are based mostly on plotted size and read time has little affect. so the cost for space being higher for ssds makes them less "profitable" than hard drives.
that being said, given the current network difficulty the roi on buying drives is very long. napkin maths cheap drives being around $20/tb, estimated mining output being 100 burst per month, and at current price easily over 2 years. sure price goes up but so does difficulty.
to me at this moment unless you have spare drives plus a machine already running 24/7, it looks like a better bet to just buy burst off the market instead of spending the next 2 years hoping to mine it. though i suppose resale value of drives would be some hedge on decrease but on increase the resale value doesn't increase.
not trying to shill, i just think sinking money into burst mining right now doesn't make sense.
