Re: [ANN] Spondoolies-Tech - carrier grade, data center ready mining rigs
S3+ ROI: 180 days
SP31 ROI: 360 days
SP31 ROI: 360 days
If the difficulty will be just a bit better than in your projections then the SP31 is clearly a winner. I can't help noticing that after the so praised ROI the S3 is doing close to nothing, while the SP31 is still doing something. Also I can lower the power efficiency down to 0.58W/GH and doing that will help me earn more money after difficulty reaches 70 billion so getting ROI will be faster than in your projection.
Care to share your projections which make the SP31 a winner? I can't find any scenario where that turns out to be the case.
If you buy 5.5TH worth of S3's you will mine ~$1200 worth of bitcoins before SP31's even begin shipping. 5.5TH worth of S3's would use about 4200W or 1200W more than an SP31.
At $0.1/kwh it would take 416 days of mining before the SP31 becomes a better deal.
As for the S3's making close to nothing after ROI, check again. (Changed it to 5.5TH worth of S3's)
