This has to do with the HFS+ file structure. HFS+ has a minimum file size of 4KB. This means that any file you create (even a text file with just the letter "a", only 1 byte large) will take up a minimum block of 4 kilobytes. Isn't this inefficient? Well, yes and no. It's inefficient because you have wasted space. However, it makes finding files easier (because the blocks of data are much larger than one byte), and nearly all files in the old Mac OS were much larger than 4 KB anyway. Now with OS X, we have several hundred thousand files, but most are still larger than 4KB and the cost of hard drives is so amazingly cheap now that it wouldn't matter anyway. I hope that helps to clear things up.
