If it can be an order of magnitude cheaper, why not? Enterprise storage has commanded a high premium for a long time and of course enterprises are storing more data than ever, not all of which needs the same performance characteristics. I welcome the shakeup in this space. The old days where you fretted endlessly over which data to preserve on expense SANs are fading behind us.
I think in general the premium goes to pay for support contracts and service as much as for the atoms and bits. Of course, it can always be argued whether those contracts and services are worth the premium, but many enterprise customers (Google being the obvious high-profile exception) seem to think so.
