In Sfard's defense, it came out before any of the new chips were officially announced so they had no idea what they were up against - and you've got to start somewhere... Even then they were just parity with what was already available (for a while), their SHA256 was equivalent to Bitmains offering at the time, and the Scrypt is equivalent to KnC. The only caveat I would give is on the Scrypt side, since the KnC's aren't generally available (except used), but then you're paying a premium for the BTC side that's not that useful. Then you have the challenge that it costs basically more than the InnoSilicon Terminator 110's (which are 2x the power consumption), and it was cheaper to just pick up one of those and a Bitmain S5.
The eco/save mode is interesting, but then the amount of money it can generate decreases proportionally, so unless you have very high power costs, it probably wouldn't make sense.
Hopefully they make a v2 chip and it's more current... Or blow out their existing chips so that it's cost effective to make something interesting. Right now it's neither (IMO).

Only, it didn't "come out". Two, maybe three miners are reported in the wild showing dubious results - hardly the "mass production" they claim

They picked a few resellers and sold them 5. It seems each one got that 5 number. After that purchase all quiet on front from SFards on chips or miners. I think they must be mining internal is my theory. They have the only modern scrypt chip, so they have zero competition right now but old gear.

No, they have the only publicly announced modern scrypt chip. No doubt there are others with chips just as efficient if not more hashing away purely scrypt. There is no way to know this. Unless you know something the rest of us don't know. I think you are underestimating how hard it is to get a new chip, and cost. For someone to do in house make a chip, then miner on scrypt for it is a pretty big task.

what about the A2 chip they only mine Script and seem to be about the same power use but only do Script Ming if you shop around you can get a 110 A2 at 28 nm chips for like 500 $ but shipping kills that deal unless you can find one with free shipping or close to you . they are big and heavy like the Zeus miners or G blacks and just as much noise but they can be controlled a lot better for less noise.

KNC cost to much we know why they are so high . I won't start with them .
The great difference is the eficience; Sfards is 4,33j/mhs, KNC is 3,80j/mhs and A2 is 10j/mhs, just a very BIG difference. The first two are for long time, the last have less choices at long term. And it must be in price.

It's a big difference in efficiency, but it may not make much difference in the bigger mining context. For example, let's say you're in Washington and getting some of that $0.02 power... An A2 will be $0.0002/MHH (megahash/hour), and a KnC will be $0.0000866. So for a 24 hour period, just picking 100MH, you'd make ~$3.11/day - the A2 costs $0.48 and the KnC costs $0.20784. So in the big scheme of things, the power cost is marginal - especially if you're paying 2x for the KnC per MH vs the A2. Either way, improving the efficiency is still a plus - and not everyone has $0.02 power.

I hope to see a miner come on market for scrypt at a fair price. And if you do find that custom one please post pics. I just have not seen a custom data center of scrypt.

I had no idea A2's would have lasted this long. It is crazy considering the amount of value they were losing daily at one point. Then no new miners I could have gotten a few months for sure out of that machine. But a ROI is a ROI i guess.

I still think the same as far as selling. I was counting on it coming out, after it didn't I just never found another rig to replace my A2 I sold. I think likely they figured out for the money they would make more off BTC gear then LTC in their data centers. But I'm just speculating. I still think there is likely a datacenter of these SF100's. Has anyone heard anything from the company at all? Do they still anwser emails?

The few minor reviews of them seem to be possitive. Sounds a lot like Sfards is the new Hashra.

I don't know about that. Hashra pumped out a ton of those when they were making profit. But scrypt gear dipped in price so much in price they became usless. Part of it is A2 was a good amount more efficient then it. Hashra/Zeus/Gaw were all really the same on not great efficiency even then.

I was comparing to Hashra since very few were ever seen and only 1 or 2 videos on them even working. They also started strong with a communication up front then nothing and Poof! "F" the Fib's and FT's of the world.

i see this thread but has anyone actually got one yet that is on here?
just wondering how it is running ....I did not get such because at 13c kwh electric made no sense.
anyway curious how reliable they are (or not) and if they are up to specs stated etc

Old Style Legacy Plug & Play BBS System. Get it from www.synchro.net. Updated 1/1/2021. It also works with Windows 10 and likely 11 and allows 16 bit DOS game doors on the same Win 10 Machine in Multi-Node! Five Minute Install! Look it over it uninstalls just as fast, if you simply want to look it over. Freeware! Full BBS System! It is a frigging hoot!:)

There have been a very few posts from owners. What I got out of it was they do work up to spec. Someone mentioned it ran hot... but we don't really have a large group so cant really say. I know I have read sucess mining on F2 pool. Not a mention of a whole lot of pools. But the few that reported said it ran as advertised. So as far as scrypt it is the best public one there is... but considering there are so few in public hands it's going to remain pricey even though LTC halved.

The only report I read said that they weren't too good: Still waiting on SFards news...
In the meantime, anyone selling at this point?
5 units sfards miner already arrive in our farm, but the quality is not as good as they promise, only 1 of them run at 1.5T/48M, all other four canot farm at promised hashrate, 2 of them canot run at all, ask other friend got similar report. already ask sfards technician to provide help, but i think it is better to wait until the quality become more stable, it will be a nightmare for our employee if a large batch of miner canot run stable

The project failed. Their chip yield is very terrible and nearly 0% yield if you SMT several these chips in a PCB. In this situation, they could not mass production the miners and sell them to the market. If they successfully manufactured thousands of dual miners, how come the LTC hashrate still no raise?

Do you have any proof? Part of it could be there are a LOT of old hashra/gaw/zeus gear that is pretty inefficient, would not surprise me if some have them unplugged unless "free" electricity. I would think it was a little higher then you said on yield as they shipped some to re sellers. I mean they had time to work on it if it was 0. They have said nothing.
