What is the difference between Mac OS Extended and journaled?
When discussing the difference between Mac OS Extended and journaled, it’s important to note that the terms "Mac OS Extended" and "journaled" actually refer to the same file system format used by macOS. Mac OS Extended, also known as HFS Plus (Hierarchical File System Plus), is the default file system format used by Apple on macOS. Journaled, on the other hand, refers to an optional feature called "Journaling" within the Mac OS Extended file system format.
Here are the key points to understand the difference between Mac OS Extended and journaled:
1. Mac OS Extended: Mac OS Extended is a file system format developed by Apple that offers several advantages over older formats such as Mac OS Standard. It supports larger file sizes, larger volume sizes, and is more efficient in terms of disk space allocation. It is the default file system format used by macOS.
2. Journaling: Journaling is an optional feature available within the Mac OS Extended file system. When journaling is enabled, the file system keeps a log, or journal, of the changes that are going to be made to the file system. This log helps to ensure the integrity of the file system and recover from system crashes or power failures more efficiently.
3. Benefits of journaling: Enabling journaling provides added data protection and faster file system recovery. When a system crash or power failure occurs, the journaling feature helps to minimize the potential for data corruption by replaying the journal log and bringing the file system back to a consistent state.
4. Disadvantages of journaling: While journaling provides benefits, it also adds some overhead to disk operations. The constant logging of changes can result in a minor decrease in overall system performance. However, the impact on modern systems is generally negligible, and the added data protection outweighs this small performance trade-off.
In conclusion, Mac OS Extended and journaled are not actually different file system formats; rather, journaled is a feature within the Mac OS Extended format. Enabling journaling provides additional data protection and improves recovery in case of system crashes or power failures.
