HFS+ or UNIX filesystem?
« on: 22 October 2002, 02:08 »
Another one of those OS X newbie questions:

When installing OS X you are given two options as you know:

A) To format your HD with the Mac OS extended file system, or

B) to format it using the UNIX file system

Can anyone please tell me whether there is a difference in performance between these two? Can you install the same software using the UNIX file systems or not? I already know that you can't use Classic if you are using the UNIX file system but is there anything more than that?

Thanks in advance.

The major drawback is no classic support. It is better for fast data access if you are running a server or some sort of system where files need to be accessed quickly and effeciently.

I also understand OSX is a bit more responsive under this system, in the end it should only be used by real UNIX dorks who are gonna be putting their comps. thrugh some heavy deuty network use, perfect file-system for an Xserve.

Thanks for the quick reply psyjax. I know about the classic disadvantage under the UNIX file system, but what about OS X software? Can it be installed if you're using the UNIX filesystem or are there any limitations to that as well?   :confused:  

Question: If I decide to use it, do I qualify as a UNIX dork? Just joking    :D  

[EDIT]I found some info here. Looks like the major drawback when deciding to use UFS instead of HFS is Classic support. But then again I don't think i'll ever use Classic so I don't really care. It also mentions the case sensitive issue, which I had gotten used to in Linux.

Anyway, has any of you tried it?[/EDIT]

now I know why i was blessed with the lack of that meta data junk that I always hated.  I have OSX on HFS+ and my home is on UFS, so I don't get bother by that meta data junk, so my files always open in the right program.

security is going to be better. performance increases noticably. running UFS on a G3 all-in-one. I tried HFS+ on one drive, and UFS on an identical one, and UFS made it run smoother. Not sure why, but it did.

it's not apps, it's the OS. Classic can't run because Mac OS 9 doesn't support UFS. The apps don't care what filesystem they're on!

Thanks for the replies guys! I think I'm gonna give UFS a try and see what happens.

I find this intriguing... I have 2 HD's, can you have one UFS and the other HFS+?

Cuz if so, I will make the main OSX hardrive UFS and run classic junk off the other HD.

Hmmmm..

honestly... i don't know if that will work. I think it can use Classic off another drive, but it's possible that running UFS completely disables Classic... I really can't say.

I'm using UFS and Jag right now. First of all I can't say that I see any differences between the two file systems except of course that Classic doesn't work. Every app works just like it did before except for Mozilla 1.1 which gives me the splash screen and then dies.   :confused:  

Anyway, I don't know if it's worth the change but if it does it's in certain areas of the OS.

Why would anyone use HFS when they can use HFS+?

Isn't the only difference the block size of data?
HFS takes up more space storing lots of small files than HFS+.

That's the only diff I'm aware of.

UFS is the UNIX file format.

I dont know much about Mac, but im aware that the UFS File System is used in BSD's. The UFS File System, EXT3, EXT2, and most the others use proper Unix permissions so i would use them over HFS any day (Dont know if HFS has them or not).

Program Compatibility
UFS or HFS make no difference to the Programs, as they just ask to operating system things like "Do me a favour and open /etc/fstab as readonly darrrrlin" and things like that, then the Operating System goes and get the file and tells the program "Ok maa, here is da file that you wheres interest'd in see'in"
"read the first line"
"the first line says..."
(Im sure your getting my drift)
