using my spare disks like this does not make sense when it apparently burns them out very quickly. i doubt i would recoup even the cost of a new drive
So if one simply plotted very slowly on an HDD with the spare space they had, it would not likely impact the expected lifespan, and they could earn a few pennies for their efforts. However the issue with all of these crypto efforts is that systems naturally trend towards centralization for reasons of efficiency. The best systems have some balance between the two. It's simply not worth it for most people to plot 100gb of free space on their laptop for Chia and earn a few cents per month. So it only makes sense for miners to do at scale.
It will be interesting to see how things centralize or decentralize going forward. When I think of the lottery I'm always amazed by the number of people that play it even with the extraordinarily low odds of winning that exist. I think there will be some equilibrium that's found for the global number of operating nodes that will be a function on the odds of finding a proof and Chia's price.
Companies have spare storage…but it sure as shit ain’t worth it to them. This is the hubris of most crypto projects: they have no real economic grasp of the problems they jump into. Amazon isn’t going to fuck around with Chia for what amounts to literal dust on their balance sheet. Businesses aren’t going to jeopardize their core competency for a couple of bucks. And the average Joe doesn’t actually have external storage space. Spotify, iCloud, Dropbox, etc. It’s all professional miners. Chia is not decentralized.

The payoff for the lottery is HUGE. So even though the EV is negative, people still do it. The payoff for Chia is comparatively small. People won’t (and don’t) care.
Which companies will adopt it and which ones won't is probably hard to determine from the outside. It should be a fairly objective evaluation though internally for a company in terms of what hardware the company currently has and what it will cost to farm Chia and what future expected value for Chia may be. Chia has somewhere between 300K - 400K full nodes operating on the network. That is objectively more decentralized than Bitcoin that has somewhere on the order of 40K - 80K full nodes the last time I checked. So I would say Chia is the most decentralized network I currently know of.

That will be a function of the price of Chia. As Chia's price increases more and more people will want to get into that lottery. A lot more people will consider farming some plots of Chia if one XCH is worth $50K compared to $250.
And Amazon has millions of nodes. That doesn’t make them decentralized.
We have no idea who owns the nodes, or what the concentration of ownership is for the top X%
I'm not going to argue about how Chia Coin works, but I'm always skeptical of claims about excessive writes destroying SSDs.
From what I understand, this is mostly unfounded fear based on the fact that earlier MLC cells were specced for a minimum of 10,000 write cycles and people extrapolated 5-10 year life expectancies from that. In practice, though, testing showed that the typical cell could be rewritten around 1,000,000 times, and the controllers would just route around the weaker cells that died early.
Anecdotally, even though consumer SSDs have been mainstream for around a decade now, I have not heard, IRL or online, of a single person complain that their SSD has failed (manufacturing defects such as the Sandforce firmware bug aside). At the same time, I've personally witnessed dozens of HDD failures.
I don't fully understand why fear around consumer SSDs is still a thing, but I suspect it's exactly the same "Reddit expert" social dynamic that drives the advice around thermal paste application.
I work with enterprise SSDs and that number is well above anything I've seen or heard, even from the manufacturers.
It seems I misremembered the quantitative data, but the overall qualitative point (SSD Endurance is much, much higher than most "prosumers" believe) is accurate.

> The one thing in common will be that you need high endurance, due to the fact that it take almost ~1.8TB of writes using the -e flag or 1.6TB without that option to create a single K=32 plot.
> Endurance is how much data can be written to the SSD before it wears out. In Chia this is important because a plotting SSD will generally be at 100% duty cycle and writing all day.
> A mixed use or high endurance data center or enterprise SSD is the best choice for plotting. Used SSDs with plenty of endurance can be found for a good value on eBay, Craigslist, or similar.
> Consumer NVMe SSDs are generally not recommended due to the lower endurance, and they often employ caching algorithms to faster media (SLC, or single level cell) for great bursty performance. They do not perform well under heavy workload sustained IO. There are very high performance consumer NVMe SSDs that will offer great plotting performance, but the lower rated endurance in TBW will result in a faster wearout.

It’s like a farm burning some of their crops to generate a bit of hot air for wind power. Like, you can do it and it gives you that small amount of power but you’re literally destroying the resource and probably cause a lot of waste in the system as a whole.
Chia is like Bingo. Generating the Bingo cards can put a lot of wear on an SSD, but once you have the bingo cards to fill up whatever space you have, you can play for nearly free.
I haven't done the calculation myself, but I've read that it's no longer worthwhile to generate new cards. If so, that means most of the damage has already been done. It's a sunk cost.
But the people who are already in the game can keep playing indefinitely. If prices are too low to even do that, they could back up to tape and go offline for a while.
In the meantime, my operating cost is running the NAS (which was going to be powered up anyway), and some CPU power to handle the farming (not even noticeable on a Ryzen 3900X).
