“Sometime next year, Apple will start using a new file system on all its hardware,” Edward Mendelson writes for PC Magazine. “The new Apple File System (APFS) will replace Apple’s old HFS+ file system, used on all Macs since 1998 which in turn was based on the archaic HFS, introduced in 1985.”
“For now, APFS is available in the developer beta of Apple’s next-generation OS, macOS Sierra,” Mendelson writes. “Most users won’t notice anything radically different about hardware with APFS on the hard disk, but a lot of subtle differences are hidden below the surface. Most notably, APFS uses integrated encryption instead of the essentially tacked-on encryption technique used by the existing OS X FileVault feature that slowly encrypts or decrypts an entire drive. APFS can encrypt whole disks and individual files with separate keys for the file and its metadata, giving granular control.”
“Apple’s current file system time-stamps files with one-second precision, not enough to keep track of file changes with today’s hardware. APFS time-stamps files with one-nanosecond precision,” Mendelson writes. “Other advantages of APFS disks include flexible space allocation, so that two APFS “disks” can borrow disk space from each other when they need it, and not be limited by the space allocated to them when they were created.”
