We will not force you to use RAID and we do not have plans to invent a wheel (a new brand RAID implementation) and include it to the storagenode code. However, you are free to do so, if you believe it’s economically viable.
If we increase payouts for SNO who selects to invest in not necessary hardware, we should increase prices for customers, and they could become uncompetitive with centralized cloud providers like AWS, Google or Azure, so it’s a last option to consider. There is no benefits for customers in your super reliable setup, the network itself is handling that, independently of reliability of each node.
I would not start this discussion again, the thread RAID vs No RAID choice is waiting for you
