The New Mac File System: It's all about Speed and Security
At its WWDC developer conference, Apple revealed that its latest macOS system, High Sierra, will run Apple File System (APFS). Apple claims that High Sierra is its fastest operating system ever, and Apple File is part of that, offering much better performance and security than before. Along with the speed, APFS supports far more files than ever, letting you put nine quintillion of them on a single volume. Security-wise, it includes multikey encryption, making it tough for bad guys (or law enforcement and spies) to crack even if they have physical access to your drive. Apple File is arguably a more important update on macOS than other devices, because a lot of folks lean on their Macs for disk-heavy tasks like video & photo editing. Apple says that the new advanced file system is "optimized for modern storage," including fast SSDs and flash, Lightning and USB drives. The new file system will arrive sometime in September at Apple's usual iPhone event with the launch of macOS High Sierra.
