Consider if those are prices for worthless lossy storage.

   ?  Why would they be lossy?

     Chia depends on the miner being able to find precomputed
     answers on storage, if that storage is constantly evaporating
     the miners data out from under them, the miner has no answers,
     and has to waste even more time-energy-money backfilling
     those holes in their rainbow tables again.

   Honestly, I briefly made a script to plot on sia's free unlimited
   storage mirrors some time ago and the problem ended up being my
   personal bandwidth.  It took me more than the time of a block to
   personally download enough data to make noticeable money.
   Filecoin's free storage is at [1]https://nft.storage .  Free storage of
   unlimited data that is important to the world, in 100 MiB chunks.

     Then also consider if those prices meet the hard economic reality
     of actual long term raw storage pricing, versus being subsidized
     by foolish investor rounds, loss leader sales promotions, etc.
     Today, $685 / 18 TiB / 12 mo / 5 yr = $0.6343 per
     TiB-month-lifetime.

   Is this the lifetime of a rotating disk?  Have you considered bulk tape
   storage?  What about Moore's law?

     At $0.03 per T-m[-l?], FileCoin is clearly a counterparty bankruptcy
     risk to your data. Even if people are yield farming their otherwise
     unused disk extents off their home and business hardware into
     FileCoin for fun, those users are pricing their slack space way
     too low to ever buy even a pizza with their earnings.

   Every blockchain starts this way.  People like making a few cents, some
   are passionate and have existing capital, others have a business plan.

     SiaCoin and Amazon are pricing closer to reality after
     export costs and profit.

   Unlike Amazon, sia's and filecoin's price is decided solely by
   individual sellers and buyers.  If those prices are real, then somebody
   is pumping sia or trashing filecoin, or both.

     The sweet spot between price, capacity, watts, chassis volume,
     speed, etc is always moving.

   Certainly true.

     It's also the world's most energy efficient SSD, drawing as little
     as 0.1 Watts per TB, which is about 80- to 90-percent lower than the
     competition.
