What PaulHavs said !
There's no HA on the DataCore, hence no inter node mirroring and no latency, it's basically direct attach storage and also has other single points of failure within the system to reduce cost further. Add resilience, high availability and networking and you more than double the cost, increase the latency and reduce the overall IOps. So not really comparable to other SPC-1 submissions.
Chris you should know better by now.
