My understanding is that while ZFS might be a great fit on the desktop, but it's way too RAM hungry for phones/ipads. Maybe with Apple contribution it could work better on mobile? Maybe I'm just ignorant of different tuning or features that could be disabled? I've only used it in rather simple scenarios.
APFS was pretty explicitly designed for mobile, so I wouldn't be surprised if ZFS had been adopted on desktop they still made APFS for mobile.
- happymellon 6y agoI use ZFS on my RaspberryPi. It works great even in lower RAM situations.
- pfranz 6y agoApple has historically be very stingy about RAM in iPhones. It looks like modern RaspberryPis today have 2, 4, or 8gb. The current-gen iPhone SE has 3gb, 11 standard/pro/max have 4gb. They're in the same ballpark. So it is possible, but Apple is so incredibly focused on mobile I can see them still investing in a custom filesystem focused on SSD, low memory overhead, per-file encryption, firmlinks, and whatever custom stuff they add for system updates, securing the boot volume, etc.
- happymellon 6y agoMaybe, but that didn't stop them from ZFS on the Mac.
- centimeter 6y agoThese days it works great on low ram devices. My router runs ZFS on openbsd and uses maybe a 1-200 hundred megs for FS stuff, at most.
- Tom4hawk 6y agoI've tried to look it up and it seems that ZFS doesn't work on OpenBSD. Is it some new development?
- centimeter 6y agoOops, I meant FreeBSD, haha.
- Tom4hawk 6y agoOh, makes sense. Thanks for clarification!
