Come on people havent you seen chia and hdd price?you can buy bunch of chias for that money which that hdd will never mine in whole life.
I agree here as with HDD is much different than with GPU-s,while I still mine with GPU-s hoping these new coins will be worth much more than they are now,it is a completely different story with HDD mining,you can't mine any other coin except CHIA or other choices are very limited here so it does not make sense to setup your server to mine CHIA,running a lot of HDD-s requires resources like a good CPU and RAM and in the end this setup cost much more than any CHIA you can mine,so I only agree in HDD mining is not worthy it is better to buy coins but in GPU mining for me it is a completely different thing.
chia is not mining it framing use little resources it like you can use raspberry pi but progress before faming it use a lot of power and good cpu and ssd for plotting faster.
