Anyone who've heard or read Linus Torvalds - would know, he is pretty tuff when it comes to complementing someone's else work. Though Linux is amazing in its own but if you keep on bashing your competitor, someday it will strick you back. Recently, and previously he made a comment calling "Apple’s filesystem is ‘complete and utter crap". It's built on 25-year old technlogy that stood by the test of time, through multiple OS versions and a change in hardware technology culminating in a now UNIX-based architecutre. Mac OS X is an amalgam of FreeBSD and NexT. It's HFS+ filesystem isn't ext4 but it has its own features that are pretty good.
Here is a quick comparison between these two:
- Maximum number of files per filesystem: Four billion.
- Supports volume sizes to 8EiB.
- Supports file sizes to 8EiB.
- Journaling.
- UNIX file permissions and ACLs.
- Transparent Compression.
- Transparent Encryption.
- UNIX filesystem layout.
Ext4 Features
- Maximum number of files per filesystem: Four billion.
- Supports volume sizes to 1EiB.
- Supports file sizes to 16TiB.
- Journaling.
- UNIX file permissions and ACLs.
- No Transparent Compression.
- No Transparent Encryption.
- UNIX filesystem layout.
So, you see, by comparison on some significant metrics, HFS+ is comparable to or superior to ext4. I do find it considerable overkill on the part of both that these filesystems can address more disk space than is currently available on the entire planet. As an illustration, if you could magnetically format the Moon (1 Lunabyte (LB)) and find a USB cable long enough to reach it, you could use the Moon to store your illegally downloaded MP3s, movies and porn–for everyone on Earth.
Why did Linus make such an incredibly crazy statement? Jet lag? Hangover? iPhone malfunction?
