Mac OS Extended

Mac OS Extended refers to the file system used by Mac OS 8.1 and later. HFS+ represents an optimization of the older HFS file system by using hard disk space more efficiently. As hard disk capacity increased over the years, Apple realized that they needed to improve the space-saving capabilities of their file system. Building off of HFS, they increased the number of blocks from 65,536 to 4.29 billion. With HFS+, you are no longer limited by block size. Now, for example, if you have a 4K file, it will only take up 4K of space.

Guidelines for Choosing Mac OS Standard or Mac OS Extended

This is actually a fairly easy decision. You should only use Mac OS Standard if you are creating a volume smaller than 32MB, you are using a Mac with a 680X0 processor or you are creating a file structure that will need to be used by Macs using Mac OS 8.0 or earlier. Otherwise, you should select Mac OS Extended.
