At the outset I would like to do mine to do support my site with bitcoin And sell surplus of bitcoin
now i find all most 4 device
1_ spondoolies divices with 5.5 TH/S
this is description from official site
The SP31 included an improvement to the ASICs that delivered more hashing for the same power consumption. With the SP35 we replaced the PSUs to squeeze out even more out of the RockerBox ASICs. This new design will deliver 5.5TH/s while maintaining a slim 2 U case suitable for both home and data center hosting. Note: With the current power draw the SP35 is only suited for 208V and above power outlets.
