When we built Internet, there was already microbashing. Over the 30 years, it blossomed in typical human nature to “preach about something I have absolutely no idea about, but strong desire to look smart. Any opposition to call troll or clueless.”
Study of HR IT department:
- all about efficiency, and price per plot - there are many crypto kids bragging with fancy HW. Simple question such as “What is your price per plot?” is followed by mental diarrhoea. If you do not know how much you spent, how do you know how much you earn?
- right here, right now is all you need to focus on - what is in your pocket, ready to reinvest
Our tourist, simply resalable, plotting rig spits every plot in ~19min @ 0.05$/55W/plot with capacity >78 plots/day.
BSgument #1 SIZE matters…perhaps in porno industry
From official Chia Wiki, we have found out there are no real advantages to go over k32 at the moment
. We understood that larger plots are simply:
- k33 = 2.06 x k32
- k34 = 4.24 x k32
RESULTS of study of plotting based on this post because it really doesn’t matter. Same machine will have same multiplier no matter what.
plot | min | time multiplier | k sizes GB | k sizes multiplier | advantage |
---|---|---|---|---|---|
k32 | 28.1396 | 108.9 | |||
k33 | 70.5466 | 2.50702213251077 | 224.2 | 2.05876951331497 | -17.88% |
k34 | 179.457 | 6.37738276308121 | 461.5 | 4.23783287419651 | -33.55% |
Result is simple, IT IS BETTER TO PLOT MORE k32 PLOTS THAT fancy >k32 plots.
We have 6 x LVM2 JBODs 100-140TB, each VG has got 1-30GB free space used for blockchain/server backups. We see no economical advantages to fill space “effectively” with ineffective plotting of >k32. We currently purchase 14.7$/TB.
BSgument #2 about “old dual CPU, high RAM DDR3” servers. We have heard kids talking about 600$ old dual CPU server with >256GB plotting ~15min/plot. We asked simple question “What is your price per plot?”
We have got typical answer “I do not know man, 450-600Wh…it is cheap initial cost…who cares” We wonder no more, why there is poverty on Earth.
If someone has got free electricity, we understand. Sadly, we paid 0.23$/kWh this year, and from next year we get lovely hike to 0.31$/kWh
We currently plot for 0.05$/plot because doesn’t exist storage system to do anything economically on such old inefficient HW. We used to have Dell T5500 dual Xeon that burnt 500Wh
We do not calculate HW costs because the used HW we bought will be resold few years later for almost same price as now.
Only consumables are energy, NVMe for hybrid plotting.
We are currently 54W/plot/0.013$/plot + latest NVMe capable of 600TWB or 1500 plots or 0.087$/plot (Popular Corsair MP 600 2 TB gives 0.03$/plot)
There are no used datacenter U2/PCIe drives available in our area, and new ones are beyond our profitable usability.
Intel Optane 900P capable of sustainable 2TBs write, still cannot beat good old Corsair MP600.
Putting storage system aside:
rig | W/plot | $/plot |
---|---|---|
HR | 54 | 0.012 |
no idea guys | 112.5-150 | 0.026-0.035 |
HR Rig:
component | price $ |
---|---|
MB B550 | 180 |
Ryzen 5950X | 400 |
RAM 128GB | 600 |
PSU Platinum | 300 |
TOTAL | 1480 |
RESELL PRICE | >600 |
We do not feel any savings in old inefficient HW. Quicker one plots, more it all costs. We have seen some kids working on GPU plotting…allegedly 9 min record right now.
Any kind of mechanical HDD can do ~150MBs, slightly above default 1Gb ether nowadays. Each plot takes ~15min to upload.
Anything <15min plotting time needs >2.5Gb ether (while our workstation already has 2.5Gb, no server has it as standard. Our old SuperMicro mini server for farm did cost 200$) , large cache because no mechanical HDD manages to do sustained 200MBs…You will be stuck at ~10min anyway.
Bottom line is always ROI (Return On Investment). We all do it for profit.
