We could say that FAT is the universal format. But the problem is that today there are many computers and we cannot know when we are going to use it in one with another operating system, so it must be clear that if we format it in Mac OS X Plus we will not be able to read or write on it on another computer. If we format a hard drive that we are only going to use on Mac computers, it is most likely that this is the best format we could use, since everything is faster and works better. This is the Apple format, to put it in a quick and easy way.
