Apple migrated its users to a new, modern file system called Apple File System alongside the release of macOS High Sierra 10.13 back in September of 2017, aiming to take advantage of flash and SSD storage drives, almost primarily because of the fact that all new Apple products use SSD as the storage disk.

Support Communities / Mac OS & System Software / macOS High Sierra. I've barely used APFS much less APFS encrypted. Feb 27, 2018 10:24 PM. Ever since the first beta of Sierra (Mac OS 10.12), I have been interested in Apple's new file system, APFS. As the first new file system released by Apple in almost 30 years, I knew this file system would be built from the ground up using the best techniques for providing speed, reliability and features found in modern file systems.
This file system is specifically designed for Apple products but that doesn't necessarily mean that other files systems are bad, just that they serve other purposes. It was announced at Apple's Worldwide Developers Conference in 2016 as a replacement for the then default Hierarchical File System Plus (HFS+) file system. Apple released APFS (Apple File System) for mobile devices on March 27, 2017, along with the release of iOS 10.3.
Migrating from HFS to APFS
APFS replaces HFS+ (also known as Mac OS Extended), Apple's proprietary file system that had been used for decades and which builds on the original HFS, referred to as Mac OS Standard. HFS+ was designed in an era when floppies and hard drives were the best storage technologies. But since then a lot has changed: almost all Apple products use SSDs, and the next-generation storage technology is continually evolving.

APFS Key Features: Encryption
The new APFS was developed with encryption at its core, likely due to Apple's requirements of using the same file system across various devices; consider multiple user keys within the file system on iPhone or iPad, or single-user keys on portable computers. According to Apple's documentation, APFS supports the following encryption models for each volume in a container:
- Unencrypted
- Single-key encryption
- Multi-key encryption with per-file keys for file data and a separate key for sensitive data.
The latter is particularly important for fully encrypted portable devices, but unlocking the iPhone or iPad gives the user access to additional keys and, as such, additional data.
Snapshots
By taking snapshots of the whole file system at a certain point in time, macOS essentially freezes a point in time that it can always revert back to. Every change made in the file system is then tracked and compared to that captured moment, and only new data takes up additional space. Essentially, it creates a read-only, independently mountable clone of the file system and saves the changes in a new location to preserve the integrity of that clone.
Space Efficiency
How many times have you struggled to optimize your Mac's storage Joker poker strategy. by locating duplicate files and folders? The new file system now allows users to store data more efficiently, so if you copy a file to a new folder on the same computer, no data is actually duplicated. What happens instead is that the metadata is updated and the on-disk data is shared between locations. Changes in the ‘copy' will trigger new space allocation, called copy-on-write, which also ensures that updates to the file system are crash protected.
While you might wonder why someone would create a copy of the file on the same computer, the average user might be tempted to keep a copy under a different name, such as 'presentation-draft,' 'presentation-1,' 'presentation-final,' or 'presentation-typo' when working on a Keynote presentation. Users working with larger files – such as video editors – might also see APFS' space efficiency as a huge advantage.
Performance
Since APFS was developed for flash drives, it includes TRIM support. With this new file system Apple is also focusing on avoiding frustration among users caused by the annoying beach ball of doom. To do that, Apple uses I/O QoS (quality of service), which has the system arrange tasks into priorities, and obviously focuses on resolving the processes that are immediately important.
Apple applies a three-point protection method to ensure data integrity:
- All SSDs and hard drives used in Apple products use Error Correcting Code (ECC) to check for transmission errors, and corrects them.
- APFS uses the copy-on-write scheme.
- APFS uses the Fletcher's checksum algorithm for metadata operations.
The Negatives of APFS
Though there are a lot of benefits of using APFS, there are some drawbacks in making the switch from HFS+. While it is mandatory on Macs running High Sierra 10.13 or above – though the conversion process can be skipped with the right know how – it's worth being aware of what will change with the new file system. The negative points of APFS are:
- It doesn't provide checksums of user data.
- It doesn't take advantage of byte-addressable, non-volatile random-access memory.
- It doesn't support compression.
- It doesn't support deduplication.
HFS+
With APFS Apple moved away from a file system it had used for the previous 30 years, HFS, which was introduced in 1985. Apple improved the original HFS in 1998 with HFS+ by adding support for much larger files and Unicode for naming files. It also utilized a full 32-bit allocation mapping table instead of HFS's 16-bits, increasing the allocation blocks to four billion. Despite its welcome benefits, the HFS+ lacks features that are considered highly important in modern file systems, including: data checksums, nanosecond timestamps, snapshots, support for dates beyond February 6, 2040, sparse file support, and better implementation of hard links.
APFS aims to fix these core issues by using 64-bit inode numbers, therefore enabling better space allocation and supporting over nine quintillion files on a single volume. It also increases read-write speeds on both iOS and macOS devices, as well as the available space on mobiles due to the way that APFS calculates the available data.
NTFS
Get mac mojave. Developed by Microsoft, the NTFS (New Technology File System) is shipped as the default of the Windows NT family. While the maximum number of files matches that of HFS+, NTFS has several advantages over Apple's previous default file system: it supports file compression and data deduplication, among other features.
For some reason, interoperability between the NTFS, HFS+ and APFS file systems isn't smooth: Windows computers can only read NTFS formatted drives, while macOS can read an NTFS formatted hard drive but it cannot write to it. This gap is closed by third party drivers such as Paragon NTFS for Mac, which enables writing to an NTFS-formatted disk. However, Mac users usually refrain from using this file system unless they are working with a Windows machine.
Summing up
It's easy to understand how building a new file system was cheaper than spending time and money on maintaining and evolving a 30-year-old one. Yet despite the improvements, the new file system still has to mature, and Apple is apparently doing everything possible to speed the process up, especially since a file system can take a decade to mature. Still, APFS seems like a work in progress, because at this point it doesn't fully support HDDs and Fusion Drives. It also brings with it new problems, such as when partitioning a volume; the Time Machine's local snapshots feature doesn't allow partitioning unless these snapshots are disabled.

Whenever you are trying to partition a hard drive, you are presented with the decision of choosing its file system. A file system is required to determine the procedure of retrieval and storage of data on the storage media. Each operating system has a different set of file systems that it supports. While in earlier days the choice of the file system was limited, there are multiple options available to you nowadays. Each file system available has its own strengths and benefits to offer you. While some file systems are ideal for one type of hard drive, others are best suited for another hard drive type. You can pick any of these file systems for your hard drive depending on its type.
APFS:APFS is the short form of Apple File System which has been recently released as a new feature for the latest operating system developed by Apple, macOS High Sierra. While this file system is primarily designed and optimized for flash drives and SSDs (Solid State Drives), it can be used for hybrid or mechanical drive without encountering much trouble.
Mac OS Extended: Mac OS Extended is the oldest file system that is compatible with all versions of Mac OS dating back to 1998. It is also referred to as HFS+ or HFS Plus and is the default file system that is used by older Mac OS versions for any storage device. The macOS High Sierra, however, only utilizes this file system for hybrid and mechanical drives.
Apfs Vs Exfat
ExFAT: AFPS and Mac OS Extended only work on Macs and can't be used for other operating systems. ExFAT is the file system that is compatible with both Macs and Windows. It is thus a cross-platform file system that can be used for external drives either plugged to a Windows PC or a Mac with consummate ease.
How to Choose the File System
So, you have three different file systems that you can use for partitioning your hard drives. The following are some tips on how you can choose the best file system for different types of storage media.
1. APFS: Best for Solid State and Flash Drives
APFS is the file system that is most appropriate for flash drives and SSDs. In fact, the macOS High Sierra uses it as the default file system for these two drives. This new file system by Apple has considerable advantages over other file systems particularly Mac OS Extended. For starters, it is much faster at copying and pasting folders than the older file systems and doesn't take much time in determining the space occupied by a folder on the drive. Moreover, Apple has made extensive reliability improvements for this file system which ensures lesser instances of file corruption than in previous file systems.
While there are countless advantages of APFS, it does have its downsides as well. For instance, you need to have the latest Mac OS, macOS High Sierra, in order to write to this file system. Macs running on older versions of Mac OS won't be able to utilize this file system. So, if you want the drive to be used on Macs which don't have macOS High Sierra then you should not format them using APFS. Also, keep in mind that APFS isn't compatible with Windows so drives formatted with this file system can't be read by Windows PCs. Download free sims games for mac.
2. Mac OS Extended: Best for Mechanical Drives or Drives Used with Older macOS Versions
Before the release of APFS, Mac OS Extended was the file system used by all Macs as their default file system. Even macOS High Sierra utilizes this file system as default for mechanical and hybrid drives. The reason for this is that APFS is not optimized for those drives and doesn't offer the same benefits as it does for flash and solid-state drives. Even when formatting external drives, it is a better option to go for Mac OS Extended than APFS. Another advantage that this file system has over APFS is its compatibility with Time Machine. Thus, Mac OS Extended is the most suitable file system to be used for formatting backup drives.
So, if you have a drive that is to be used with Macs running on earlier versions of Mac OS than macOS High Sierra, then you should only format it using Mac OS Extended. Moreover, all mechanical drives should be formatted using Mac OS Extended too.

3. ExFAT: Best for External Drives Shared with Windows Computers Betonline casino no deposit bonus codes.
If you make use of both Windows PCs and Macs and have an external drive which is to be plugged to both, then you can neither use Mac OS Extended or APFS. In such circumstances, you need a cross-platform solution that can be read and written to by both Windows and Mac OS. ExFAT is the best option available to you in this regard. This file system was developed by Microsoft in the year 2006. It allows you to format external drives that need to be used by both Macs and Windows PCs. This file system doesn't have partition and file size limitations like FAT32, which is the older file system that offers cross-platform compatibility.
While ExFAT is definitely the best cross-platform file system, it does have its faults. For instance, it is vulnerable to file corruption and doesn't support features like metadata offered by APFS and Mac OS Extended.
File systems are important for making full use of a storage device and determine how data is to be retrieved and saved on them. When you are partitioning or formatting drives, you need to choose a file system of your choice. Usually, there are three options available which include APFS, Mac OS Extended, and ExFAT. Each of these file systems has its own strengths and weaknesses and are different from each other. You need to decide which one is more suitable for your needs and then use it to format your drive.
