What about data integrity and crash protection?ĪPFS has atomic-level save state. Questions remain about how APFS will handle recovering storage from deleted files that have been cloned, though, since space can't be reclaimed as long as a single clone still exists.ĪPFS also supports sparse files, so storage is only allocated when it's really needed. If a partition needs more space it can claim it from the container, regardless of whether or not that space is physically adjacent to the partition.

Basically, APFS sidesteps the issue of one partition running out of space when there's free space elsewhere on the drive by creating a container around all the partitions. Will APFS help with storage spaceįor macOS users who employ partitions, AFS fixes a long-standing limitation.
This makes creating both snapshots and clones far faster and more efficient than making traditional copies. They're similarly more space-efficient at first, also not duplicating data until changes are made. It also means changes can be reverted.Ĭlones are copies of "files" (both real files and the Mac's bundled folders-as-files). It's initially more space-efficient, because it doesn't duplicate any data until changes begin to be made. Snapshots create a read-only copy of the system at that single point in time. Two of the most high-profile features of APFS are snapshots and clones. What Apple means by this is that APFS writes in a way optimized for solid state, and supports the TRIM command which is helpful for people who delete a lot of files and like to keep a lot of space free.

That's the flash storage chips inside Apple Watch, Apple TV, iPhone, iPad, MacBooks, and high-end Mac desktops.
How does APFS better suit SSDs?Īpple says APFS has been written with solid state storage in mind. It also does fast directory re-sizing, which means you shouldn't have to wait to see how big a directory is, if you're in the habit of looking. That should minimizing beach balls and spinners. So, it prioritizes things like app launches and data delivery. APFS does several things to make Apple devices feel faster.ĪPFS, for example, focuses on low-latency. It's faster to reach for a drink on the table next to you than to have to get up and go get it from the fridge. Will APFS be faster?Ī great deal of speed has to do with perception. That should allow for a single code base with fewer resources need to develop and maintain it and allow it to grow faster and better. That means different source code and separate maintenance and development.ĪPFS was designed to scale more consistently across Apple's platforms, now and into the future. While HFS+ runs on all of Apple's current devices, from Apple Watch to Mac Pro, there are differences in how it's been implemented across those devices, including key areas like encryption. Sometimes, to make it to the future, you need a fresh approach. Running in the red, maybe, held together with bubblegum and paperclips, but running.īut running in the red is no way to get to the future. Through it all, HFS+ and its valiant crew have kept it running. We've gone from rigid, single-threaded data structures to more flexible approaches.

We've also gone from hard drive platters to solid state disks, from physical installs to digital downloads, and from manual backups to Time Machine and iCloud. Since then we've gone from the Mac to iPhone, Apple TV, iPad, and Apple Watch, from a few million devices to over a billion devices, and from kilobytes and megabytes of data to gigabytes, terabytes, and beyond. HFS+ has been around since 1998 - almost twenty years ago - and has been updated and McGyver'd in almost every way imaginable since then in order to try and keep up with the demands of modern computing.
