I just bought an external hard drive of 320 gb. The default format is FAT32 and I was wondering if it is a good idea to format it to a more modern filesystem.

It is only going to be used with a MAC OS X machine, I don't need windows support.

I was considering:


What do you think?

Yes. If it's going to be used with OS X, use the Mac's disk utility to format it HFS+. There's no reason to use NTFS or ZFS if you're using OS X only.

Not to mention that NTFS has (by default) no write support on OS X, and I don't even know about the current state of ZFS there. – Sven May 2 '11 at 15:32
The best reason to change it is the individual file size limits and other sacrifices made for cross-compatibility in using FAT32. If you're using only one OS with it, use the OS's native filesystem. Makes everything a lot easier. – Bart Silverstrim May 2 '11 at 16:36
