Can anyone clarify for me why/how this incentivizes SSDs over HDDs? Seems if it's really just about having "proof of space", whatever HDD is cheapest would make sense? How much data gets read back how fast during validation?

It's the initial generation of the 'plots' that make up the proof of space that's disc IO limited. So faster SSDs for that and then moved onto HDDs for long-term. According to Chia, it uses 332 GB to generate a 101.3 GB proof of space: https://www.chia.net/2021/02/22/plotting-basics.html https://www.chia.net/2021/02/22/plotting-basics.html

  So just need a computer with 350GBs of ram?

    That works of course, but RAM also costs per gigabyte an order of magnitude or so more than SSDs.

      Doesn't wear out though. Question is will they require more ram in the future once 350GBs becomes cheap?
