> Mail (super nice due to compression and big space savings (in my case 20% reduction of space needed) Things will get even better once zstd is added[1]. Leaving transparent compression out of APFS was a real big mistake by Apple, imho, given how fast and cheap lz4 and zstd are. It's one of the reasons why I have a ZFS volume set aside myself.

Flash storage might be the highest-margin component sold by Apple, so there's a conflict of interest with filesystem features that reduce the need for storage.

  That seems a little tinfoil hat considering the largest consumer use of storage is photos & video, neither of which compress any more anyway.

    Macbook Pros have use cases which extend well beyond photos & video.

    And that Apple is heavily pushing the HEIF/HEVC formats in ways that provide similar image quality with lower storage uses.

      This is a macOS thread, but it would be helpful if Apple allows micro SD cards to be connected to the lightning port of iOS devices.

        That is mostly limited to copying photos and videos to/from the "Photo Roll". There are many thousands of applications which process other file formats. Some of them have natively implemented support for a 3rd-party (expensive) storage device called iXpand, which itself comes with a poorly implemented app. These third-party applications are poorly and pointlessly (re) implementing basic OS file system I/O functions. Is it possible that these pointless I/O hoops are hampering uptake of $1000 iPad Pros for "laptop" use cases?

lz4 and zstd are cheap in what? CPU cycles? Apple cares more about energy use these days (correlated but not equivalent), maybe it's not a good tradeoff?
