So this is pretty simple setup. My server is an IBM x3550 m4 with dual xeon e5-2670 chips, 80gb of ram. I am using netapp ds4243 24 bay enclosures that house 2tb 7200rpm enterprise drives. So in total this setup is 240tb (slightly less because of usable space. These enclosures are supposed to be used with a netapp controller. I didnt want the added expense plus dealing with their software licensing. They are qsfp so I bought a standard LSI HBA card and a qsfp to mini sas cable and plugged the top enclosure into the card and daisy chained the rest of the enclosures with their standard qsfp cables. I don't run any raid so these are all just stand alone drives. I plot each one so that if a drive goes down I can revert to my notes and just replot its replacement with the exact plot numbers that was on it.
I can plot 4 to 5 drives a day. I get about 32k nonces per minute optimized with my chips. My main bottleneck when it comes down to plotting is my disk write speed. I am only getting about 80 or 90MBps. I dont think its my drives as most of them are rated for 150MB write speed or above so it could be the back plane on the enclosures themselves.
I ran the setup with windows server 2016 and with ubuntu 16.04 and ultimately went with ubuntu. My nonces per minute were a little better with windows but my plot times were significantly slower so I went with ubuntu.
That is a nice setup; 240 tb is a lot of capacity. Are you using Creep Miner?

I have been working on setting up a burst/any other coin HDD farm for a bit. I was able to purchase a Synology 8 bay NAS and tried writing to it, but it was so slow that it would have never finished. How do you go about plotting on a NAS? Can you give some details on your build? What hard drives are you using and what NAS's? What are the specs of the computer you are using to plot/mine from? What is your current investment into that? Any advice/help would be appreciated. Plot on a local hard drive, make sure the plot is optimised, then copy that plot to your NAS drive. Repeat as needed. Same concept is needed, but a lot MORE so, for those that do BURST mining via cloud storage. All of my BURST mining is done on local HDs on machines that are also GPU mining other stuff, though - for me it's more of a "well, I got all that empty space on the drive, might as well get SOMETHING out of it" thing.

Your setup is beautiful. Maybe I can get one of my friends who actually understands those words to get something set up for me. If anyone is interested I would pay them for their efforts.

Thank you. Roi is a little hard to pinpoint because of how long it has taken to plot and the changes in the network. Now that I am fully running it will take a little time to really see what I will be generating each month.

Now that I am fully running it will take a little time to really see what I will be generating each month. Here is my thought though. I think decentralized storage is the future. It can be done at incredibly cheaper prices than the big companies can, and to get the infrastructure built now would give a huge advantage over the years as newer and better technology come out. Burst is probably the most profitable currently, but Siacoin and Storj have some potential, but both have problems to work through as of now. I love the idea of running racks of hard drives and being able to throw some capacity whichever way has a new startup, if it tanks, you aren't out a whole lot, if it blows up, there is huge potential, and I think one of them eventually will blow up and be huge.

There is basically no ROI right now with sia or storj because there is not enough demand. One good thing with equipment investment is you can resell for a good chunk of what you paid, hard drives arent like asics where they become valueless. I shot you pm if you want to get back to me there.

GPU's still lose value, although slower than ASICS, but hard drives will retain value even longer than GPU's. Storage is getting harder and harder to shrink, so I think an investment would return its value even longer into the future.

Burst is probably the most profitable currently,
BURST isn't decentralised storage, that's STORJ or MAID (and SIA? Not sure there). Storage isn't that hard to shrink, it's just EXPEN$IVE to do so right now. Intel showed off 60 TB (yes, SIXTY TERRABYTES no typo) in a 3.5" form factor last year - issue is that it was a SSD and probably WAY pricey. I don't think it will happen real soon, but SSD will probably replace magnetic HD storage eventually - it's already there in niche usage, just not quite price competative on a per-TB basis yet. My current estimate on ROI for a Seagate Archive 8TB (which is usually the lowest price per TB on new drives) is around 20 months, unless the price starts climbing faster than the network total TB does (price has been DROPPING like most altcoins the last 2-3 weeks, while network capasity keeps climbing). There are calculators, but they are ALL on the optimistic side as due to how BURST pools work, only *one* machine pointed at the same "address" gets counted for total capacity on that pool. There are times the pool thinks I only have a few hundred MEG of capasity, even though my total among all of my machines is probably 20 TB or close. Up side - BURST doesn't use a drive particularly hard, so they should have good longevity in BURST usage. Another up side - I have to buy a drive anyway when I'm building a new mining machine, and the cost of buying a 3TB HGST refurb isn't much more right now than buying the cheapest drive available, so the difference in price will pay off pretty quickly.

You are right the calculator is optimistic and its a long term average so that has to be taken into account. However, it doesnt matter how much space the pool is "registering" for you. What matters is the amount of nonces your miner is mining. So whatever the space the pool shows you having is inconsequential so long as your miner is mining the actual space you have, looking for Deadlines to submit to the pool.

Just saying that's why all the calculators are optimistic, not that my other machines aren't mining and submitting deadlines.
IME the calculators seem to be 30-50% on the high side, even on the long-term - and a LOT more than that if you never find a block.

I am not the expert but I don't think HDD's will ever disappear. Not unless they make SSD's as durable as HDD's and cheaper. I probably won't wear out a SSD in my life time but the risk is there. (for now) And there is also HDD's being cheaper than SSD's for per gb/$ Side note: I recently bought a WD 1tb external usb3.0 hdd and it is as fast as (maybe even faster) the first gen SSD's. (tested with "HD tune" software, +200mb r&w/sec) HDD's are still developing technologically.

I've been using SSD's for a few years now & I have found out 1 thing........BACK UP AS OFTEN AS POSSIBLE......there is no way to recover data (cheaply) from a dead SSD Spinners usually work just enough to get the data off em by hooking them up in another PC as secondary drive....no such luck with SSDs for me at least Read the reviews on Newegg for any SSD you want to buy,they are spot on,on how that SSD will be in the long run
