Apple apfs vs mac os extended2/7/2024 I shelled out a bit of cash for my T5s so its something I want to pay a bit of attention to. My internal and external SSds all have a lot of free space and I'll be keeping it that way. Ive also read thats it's a good idea to keep these at least 25% free. I've also read that modern well known brandnames' external SSDs manage their own garbage collection and though used on its own is not as efficient as in conjunction with Trim, its apparently enough. (Theres a lot of conflicting info) The SamsungT5s apparently do support Trim but only from Windows. We can safely leave it to Apple to manage internal SSD, but obviously we want to keep our external SSDs in optimal health IF this is a potential problem. as in better ?" Better in all you mentioned yes, except possibly wear and tear on external SSDs because *reportedly*, MacOS doesn't support Trim over USB, which as I understand, is an important part of maintainance along with garbage collection. ![]() According to, "Mac OS Extended (Journaled) is also HFS+, but it has an extra mechanism that avoids corruption of the file system when something bad happens, such as loss of power during a write operation." If you watch the YouTube video, you will notice he uses HFS+ to compare to APFS. So this file system is better at not losing bundled data than previous ones. ![]() APFS bypasses this POSIX limitation by performing the renamex_np. Atomic Safe-Save for document bundles: I have experienced this with macOS Extended (Journaled) where audio files seem to disappear and I have to locate them. Snapshots: Allows you to read the files Cloning: a cloned file doesn't take space (it might take up a little bit of space because of metadata) Copy on Write (COW): saves space, prevents crashes, and boosts speed not a new technology, but its different how Apple is using it ![]() The advantages of APFS include: Optimized Performance: APFS is designed to take full advantage of SSDs, providing faster read and write speeds compared to older file systems like Mac OS Extended. Space sharing: allows for fluid volumes of data, unlike the rigid ones in previous file systems APFS is ideal for internal drives on modern Mac computers, especially if they use solid-state drives. Compatible from the Apple Watch to the Mac Pro (not MacBook Pro, Mac Pro)įeatures (watch the YouTube video to learn more about these features): A quick Google/YouTube search could answer your question, but if you want my help here it is:
