Apple File System - mac OS High Sierra first tasted

Apple released the latest operating system macOS High Sierra on June 6. It is available at this fall, at that time, users can download and install presumably in this fall. The system uses a new file system, Apple File System.According to Apple, it uses a new 64-bit architecture that designed for today's flash technology, and also ready for tomorrow's new storage capabilities. With Apple file system, duplicating a file and finding the size of a folder's contents faster. Enjoy even more peace of mind with built-in encryption, crash-safe protections, and simplified data backup on the go.What about it? Let us experience as soon as possible.

Hardware

  • iMac(21.5-inch, Mid 2011)
  • Processor 2.5GHz Intel Core i5, 4 Cores
  • L2 Cache(per core) 256 KB, L3 Cache 6MB
  • Memory 4GB 1333MHz DDR3
  • Graphics AMD Radeon HD 6750M 512MB
  • Storage 500GB SATA Disk

Install

This size of install package is 5.26GB,  after half an hour, High sierra was success installed.


Amazing, in first sight. How about you?

Let's see this file system information.


Above file system information, the new Apple File System is also called Mac OS Extended(Journaled).That said the new file system was be optimized internally, such as 64-bit.

Then I will do some performance test. With the new file system, I should  feel faster and more efficiently. I will test boot speed,calculate size of folder and the speed copy files.

Boot speed

Several generations of Mac OS start speed is very general, I feel fastest one is 10.6. Next system has been optimized, but none of them can reach MS Window 10 start speed(less than 30 seconds). MacOS High Sierra with a new Apple File System, will be more quick?

Let's  see. I choose two Mac OS System with hardware environment consistent, the one is Mac OS Sierra, the other is Mac OS High Sierra. Timing from the beginning to hear the sound, to enter the desktop. How about the result?

  • mac OS Sierra 63 seconds
  • mac OS High Sierra 66 seconds

YES, No surprise!

Calculate the size of folder

First, in the Mac OS High Sierra, choose two folders to calculate size, the one is the library folder under the start disk of Mac OS High Sierra system,  the other is the library folder under start disk of Mac OS Sierra. Then switch to Mac OS Sierra, choose the same folders.

  • In Mac OS High Sierra, High Sierra library cost 19 seconds, Sierra library cost 31 seconds 
  • In Mac OS Sierra, High sierra library cost 8 seconds, Sierra library cost 37 seconds.


The result is unbelievable. It may be old hardware.

Copy File

First, In Mac OS High Sierra, copy a file with 5.26G from third-party disk to desktop. Then switch to Mac OS Sierra, copy the same file.

  • Mac OS High Sierra cost 128 seconds
  • Mac OS Sierra cost 130 seconds

Almost no difference.

Conclusion

Upgrade to Mac OS High Sierra is necessary. It's more beautiful, easy to use and support HEVC, virtual reality, although today's experience is disappointed.Maybe I should upgrade the hardware. If under the Fusion Drive, it's result as Apple said.Look forward to more experience.
