I was waiting for the Spondoolies SP30 announcement before ordering more S3s.

Each server cabinet I rent has 2 x 30A 208V outlets for a total of ~10KW, so I was hoping to be able to run 4 SP30s at 6TH/s in a single cabinet (24TH).

Considering the August / Sept batch of SP30s only runs at 4.5 TH/s and uses 3KW, I can only get 3 SP30s in a single server cabinet for ~13.5TH.

I can get 28 S3s into a single server cabinet for ~12.3TH (440 GH/s @ 350W each).

I see absolutely no reason to pre-order a SP30 over buying a S3, which is available now, even though the S3 has slightly worse power efficiency.

I hope many folks learned a hard lesson about the perils of pre-orders, and I wouldn't want to be Roadstress right now and have to deal with all the pissed off customers from his group buy. Have fun cleaning up this mess, Roadstress!

I still like Spondoolies tech, and think they make good products, but they did grossly overhype and inflate the SP30 specifications in order to sell more SP30 pre-orders. I may even purchase a October SP30 if they ship immediately and are competitive with other offerings on the market in October.
