Right - when I heard the ZFS announcement at Usenix I assumed it’d become standard a decade later when consumer hardware could handle the extra work, but it seems to have been sandbagged by the rise of cloud storage and the switch to SSDs reducing the frequency where people get corrupted data instead of all-or-nothing failures.

Apple claims that their hardware makes it unnecessary for APFS but I’m skeptical and the last time I looked the Time Machine situation was still pretty clunky. I haven’t checked Windows recently since I only use Linux and macOS.
