....errrr.... What?

Defragging doesn't really help application performance? Have the HD open a video stream. Have the HD open two video streams. Then another.... Is there any noticable difference? You are simulating additional non-sequential searches. It may have an impact if you are really hitting the drive with concurrent random requests but this rarely occurs in desktop environment.

Before you insult others... where is your evidence?

MaxPC noticed that defrag affected load/shutdown times. I can see that since the defraggers can move those relative common files to optimal locations. However, defraggers do not monitor application usage so they can't optimize the files for commonly used apps.

What the heck is going on in this thread?

I use O&O defrag because I like the way the interface looks. I don't know nor do I care if it is faster or performs better than the other programs available. It does what I need it to do and I am very happy with it. I like all of the options it gives me as well.

lol i know... i can never understand anything that guy says. Take some english classes please..

But dang O&O defrag is 50 bucks! Guess i am sticking with jkdefrag lol.

Smart Defrag is much faster than JkDefrag, and with the way my system feels after using Smart Defrag now instead of JkDefrag, I say it does a better job too.

The maximum PC test was incorrect because the benchmark they used tests not the filesystem, but the speed of reading raw clusters on the disk (a trace). So, fragmentation or the lack thereof should has no significant effect on the test; that benchmark is for testing hardware configs not filesystems. Whatever difference they got, positive or negative, was just statistical noise . The magazine editors should have known better...

They all use the same defrag API for NTFS, developed jointly by Microsoft and Diskeeper in the late 90s. But they differ in their features and algorithms for defrag i.e. resource usage, file sequencing, ability to defrag certain files (MFT, pagefile etc), speed of defrag, etc etc.

A 'deep' defrag I believe is merely a defrag for system files i.e. a boot-time defrag. It could also mean a normal defrag with free space consolidation...I don't think there is a strict definition for the term.

Very slow and does not completely defrag the drive (64MB or larger fragments are ignored by default: you need to use the CLI to force the defrag for those), but on the other hand, it has some VSS support atleast, and defrags the MFT, both of which the freeware utilities lack.

Nothing is deleted during a defrag*; files are moved around on the logical disk. But their location is not of consequence to the end user...as far as you are concerned, it's alll behind the scenes.

*If you use a non-VSS-compatible defragger on Vista, there is a chance of older system restore points being purged.

Nope, defragging does not wear out the drive since it's just another drive operation. If there is no fragmentation, there is nothing to defrag, and the defragger will not cause any file movement...unless it's a really dumb defragger.

Among the third party defraggers, I use Diskeeper 2009 Pro. It's fast and efficient and essentially a install-and-forget utility...I like the way it works.

I use Diskeeper, its seems better than the windows one. It also has this thing they called a Frag Shield. where it keeps your files from Fragging.

Frag Shield sounds like Smart Defrag's "Auto Defrag". Auto Defrag defrags when the system is idle. Is that what Frag Shield does?

Two Cables--How often should one Use the Smart Defrag? How often for the " deep optimize" option? I guess what I really want to know is how do you use the program? Thanks

Defrag programs can be quite different, but I've noticed one way or another. I used to use Symantec's Speedisk, but I switched to the one that's built in to XP, as I couldn't tell much of a difference.
