Does someone know about Google nearline and coldline storage? Google claims coldline access within miliseconds.

  > Google claims coldline access within miliseconds Well, that basically tells you almost all you need to know. It's disk in JBODs. The only question is SMR vs conventional. Anyone who knows that can't tell you in public.

    If that's how Google is implementing it, and the prices are similar, then isn't that some evidence that Amazon might be implementing it the same way?

      Amazon's latency is measured in hours, whatever process they use involves literally cold storage, either disks that are completely switched off, or some tape-like media archive system, but the article makes a good case for why it's almost certainly not tape

        It could still be normal disks, if we're feeling conspiratorial. It's easy to make faster storage slower; just add waits. Or maybe they make it take up to five hours so they can avoid peak traffic times in whatever data center your info happens to be located in.

    I think it's because even for cold storage one copy is still persisted on disk.
