Sigh ....

That Apple article is flat out a crock ..you tell me what this drive which has been "maintained" by Apple's OS will be like compared to a defragged one



versus



and then there is optimization.

Why the hell would I tell you get a product that I have zero interest in if it did not work..

This likely what your drive looks like now...



and after....



It works......up to you

or you can believe Apple and get sub- par ....up to 80% less performance from your drive

I have to agree ... defragging == good thing.

That Apple article is a) old, b) no longer updated, c) wrong.

The answer is ALL of the above. If you have a lot of files and your disk sees a lot of action (downloading, deleting, etc) then defragging is a good thing and will _never_ hurt to do it.

OP just think about for a second.....pull all your files from your filing cabinet....toss the whole lot up in the air, kick them around and out of file folders and land where ever....

a) not a single one is fragmented.

b) now go find what you want....

That's your drive head on a badly fragmented drive....

I had an interesting one the other day ....client came in with a i7 iMac 8 gigs of RAM and that drive would only test at 30 megs per second as the test could not even find enough space to run in.
Cleaned up - 110 megs per second and much snappier.

If you must defrag at least clone and test your cloned back-up before starting the process. Defragging can take awhile and a power interruption could prove at least slightly damaging.
