“…the file system doesn’t need to fill up every “nook and cranny.” Mac OS Extended formatting (HFS Plus) avoids reusing space from deleted files as much as possible, to avoid prematurely filling small areas of recently-freed space.” Ģ) Continuous appending data to an existing fileĪnother major cause, and Apple is quite right in pointing this out, was that data was frequently just appended to an existing file making it grow and ultimately become fragmented (as space runs out) and Apple has a good argument for that one as well:

Remember the concept of the big video file being split up – this is really only a problem if your hard drive is nearly full and so Apple states: Basically the author argues many points that are quite true, here is a quick summary of the points I found most important. Our friends at Apple even wrote an article “About disk optimization with Mac OS X” and there is lot of valuable information in there.

In reality the HFS+ file system in use by Mac OS X is very good at avoiding fragmentation, especially for small to medium sized files, even the makers of iDefrag admit that. So this is general theory, how about Mac OS X and what does Apple say?

a movie file) might get split in two or three sections to fit the “empty space holes” and this is the real nasty fragmentation, as it slows down your system when accessing the file. It is quite easy to see how a large file (e.g. Go back to our first comparison of the hard drive as a rectangular space and data being the little building blocks. You’d run around like a mad man… Īs files grow in size and large junks of empty space start to disappear, something else could become a potential problem. To make your life more interesting you must get them in precisely the order in which they are listed on your shopping list. and imagine you had to get the backing powder from aisle 15, the sugar from aisle 2 the salt from aisle 24 and so on.
Now imagine you need backing power, flour, sugar, salt, etc. You know, usually all the backing stuff is in one place. I would compare it to shopping in a supermarket, which is really badly organized. The makers of iDefrag give a nice example “…in these days of constant security updates as replacing operating system components not only increases the potential for file fragmentation, but also creates a more insidious problem—over time, the operating system itself ends up scattered all over your disk…” The other type of fragmentation, the one most people refer to, is the one, where files that belong together are spread around the hard drive making your computer look for all those files and “waste” a lot of time in the process. To be fair this is not what most people refer to when they talk about fragmentation, but it can become a problem in its own right. This is what many people would call “Free Space Fragmentation”. So as you fill up your hard drive, move or delete files you will get more and more empty spaces all over your storage space. As soon as you delete data, you will remove some building blocks, but the space remains empty for the time being.
When you start filling your hard drive you will add your building blocks from top left to top right, and when you reach the end start a new row, and so you continue. Think of your hard-drive as a two dimensional rectangular space and think of your data as little square building-blocks. Your hard drive constantly changes – a new email arrives, there is a change to your hard drive, visit, there is another change to your hard drive (the browser cache), when you delete something… you get the picture.
What is “fragmentation” and how does it happen? Now with Windows XP and its NTFS file system this isn’t as urgent a problem as it used to be, but it remains a habit.īeing relatively new to Mac OS X and the HFS+ file system I started to wonder whether it was necessary to do my Mac a favor and defragment it’s hard drive? I couldn’t find a defragmentation tool installed, so I started to read up on the Internet and most people kind of agree to disagree on the question of disk optimization. Users of Windows have funny habits, for example, we like to start our working days with updating the virus and spyware definitions and once every quarter or so most of us go and defragment our hard drives. In my private life there is (virtually) no room for a windows machine, though I continue to use a Dell laptop for work.

I have used a Windows powered PC for much longer than a Mac, and the Mac just blown me away.
