Hey, isn't this about the same as an SP20?  (the BTC only side).  Should I be disappointed now with the 1.7TH/s performance like I am with my SP20?  Or pay a whole bunch of money and then be disappointed?      Just asking.

SFARDS
Bitcoin single mining mode:
Hashing power 1700 GHS, power consumption 770W

Spondoolies SP20
1.7 TH/s ± 10%




The SP20, if it could do 1.7 TH/s [Not all can] would use almost twice the wattage as the SF100.  That's if you are just looking at the wattage on the BTC side of the SF100.

While the quoted SP20 rate is 1700GH, it's really more like 1500GH as a regular, predictable, not terribly efficient, and loud miner. While I like the SP20, the advertised rate of 1700GH is more a marketing value, than a practical value.

To be completely fair, we have zero idea what the realities of the SFARD 100 are in terms of sound and reliability, beyond the quoted rate and power value. Until a trustworthy guy here has put one in his home and turned it on, with a Kilo-Watt meter I'll take the quoted figures with a grain of salt.

Do we even know if it requires a power supply, and if so what kind of connection (e.g. PCIE 6-wire)? It's also unclear if the 770W (BTC only) figure is measured "at the wall" or what.

Lot's of questions to answer, and verification to happen.

Thanks!  And this part:
Litecoin hashing power 47 MHS...power consumption at wall of whole miner is 960W.

FYI... Nicehash pays this for Scrypt.  Can someone help me with the math for Scrypt (GH to MH)?  Is it even worth it?
Scrypt 0.3073 * * - BTC/GH/Day


to put this miner in to perspective  my gridminer a1 is running a 25 mhs at 420 watts or so.. this miner runs at 47 mhs at 150 watts scrypt only side  and the sha side at 1700 gh/s with only 770 watts draw this is slightly better than bitmain s5 at approx .5 watts per ghs  and not to mention you can mine both sides.. if a new coin comes out you can decide if sha or scrypt is the best in terms of profitablilty..

input your mh/s here  https://bitcoinwisdom.com/litecoin/difficulty at current diff its approx 36 ltc a month


Also put me down for the group buy.. one maybe two depending on the price.. i also sent an email to sfards.. I really like their hw. im still running the gridminer a1's

Thanks guys
Best regards

All depends on price. I could organize group for Europe people, let say 50 units for me, the rest for others.
But only in case of resonable price. I dont have good experience with previous Gridseed price policy (as G. blade for 3000USD, then soon 1500USD and no compensation etc....)

In which country are you located?
CZ

I am interested in an EU group buy as well.
same here Smiley

+1 here EU group would be nice

I would be up for a US group buy of these as well.  Of course I need to get more BTC before I can consider it, but regardless still willing to at least see about it.  Of course the pricing needs to be figured out first and foremost as I have no clue what pricing is.

I would love to run a group buy for these units but would only do so with Sfards' blessing.

If you will start a list as soon as pricing comes out, I would appreciate it.  I want to get in on it depending on price.  Also, are you based in the US?

I am in the US.

Okay, thanks. 

Not saying how many I will buy yet until we see price.

I have emailed Sfards, waiting to hear back about price and other questions.  Will let you all know when I know more.

Group buy in EU would be good but I don't think it's gonna happen.Shipping and custom fees from America to Finland are much too high.

I am also in the EU but do not want to say a group buy to the EU is never going to happen, it just depends on whether there is interest from EU based home-miners in the gear and whether we can get an impecable and reputable individual to run the group buy. Saying that, it does (on the face of it) look like a long shot .... but why not!? Short of it, there is always the resale market .... fleabay and all.

As I mentioned: I would be interested in organising a group buy with hosting. But it seems as if most miners want to have their "baby" close by themselfes, so I would join in an EU-group-buy with about 10 pce.

This would be the very best! OgNasty definitely has the skill and reputation to run a group buy, Sfards needs to give their blessing ASAP!

I would also be interested in setting up a U.S. based Group Buy.  If someone from sfards would like to make a comment on this I can go ahead and start arranging one.

I want in on it depending on price!
