Comment on Thanks a lot, AI: Hard drives are already sold out for the entire year, says Western Digital

  SSDs are way more efficient than HDDs for swap.

  SSDs are electronic, while HDDs are mechanical. This means that moving memory regions (pages) between system RAM and the storage requires:

  • physical moves, in the case of HDD
  • accessing a different region of the chips, in the case of SSD

  Imagine a scenario in which completely unrelated data access requests floods your storage drive. An HDD needs to constantly realign its needle to the requested locations, while the SSD can just re-route its data lines to that location.
