Hey everyone Brandon the Product Manager @storj here. Thanks for submitting this idea, Chris VdG has a point about the redundancy between raid and erasure coding. Our recommendation is to run one node per HD. This will actually spread your overall risk of a HD failing and losing the withholdings for that specific node ID. If you have 4 2 TB HDs then the best thing to do is run 1 node per HD and if one of those fails then at most you would only lose 25 percent of your overall withholdings amongst all 4 nodes. Instead of using raid to backup one of your nodes its may be in your best interest to just allocate that extra raid space to the network and profit off of it instead.
You won't be notified about changes to this idea.
