The drives are reportedly destroyed from the process relatively rapidly. So no, I’d probably not plan to be able to resell drives on eBay later.

it depends on the drives. CAN you destroy drives by plotting? yes. But other drives can take quite a beating - and generate 40K plots worth of data before reaching failure point. additionally, farming (serving plots) is done with regular drives, and those are very lightly read from and used once the plots are loaded.

What is "plotting" more exactly, and why does it destroy SSDs (but not HDDs)?

A better characterization would be that Bitcoin requires miners to perform vast amounts of hashing in the hopes of finding a hash that is arbitrarily difficult to find.

That's needlessly technical. The original sentence summed it up better.

Furthermore, Proof of Work is not necessarily hashing [1].

SSDs are destroyed but HDDs are not.

What about the HDD caches?

How does "Proof of Space" actually work. How do they prove the disks exist?

This is well explained in chia’s documentation. A server issues “challenges” and the harvesters respond if they have the answer to that challenge. Think of it like bingo but with a gazillion squares. The trick is that calculating the response to a challenge takes a very long time and the server only waits for a very short time to get any valid responses. So it follows that the harvesters must compute the responses in…

thanks for the explanation

Aren't they going to be using that space eventually for another distributed file system?

You are probably confusing Chia with Sia

Nah I just thought they were going to use the space for user files instead of just farming bit space to report its existence to the network

To clarify, it's the supply chain that is destroyed, not the hard drives themselves. Most Chia miners appear to be using enterprise SSDs to "farm" a plot. And consumer SSDs can't really stand up to this process long term, so they get killed relatively quick. A typical plot is around 100GB and officially takes around 356GB (and a lot of SSD thrashing) to farm. Then that plot is copied off to long term storage (larger,…

What are some examples of "enterprise SSD"? I actually would like to buy one because I suppose they are way more durable than consumer SSDs, and less likely to die on me. But the closest to "enterprise" that I can find are the samsung pro.

Something like the Intel Data Center SSDs: https://www.intel.com/content/www/us/en/products/details/mem...

They measure lifespan in petabytes instead of terabytes. Or data writes per day (DWPD).
