Defragmentation: Perfect Disk or Auslogics?

by susanherna / June 7, 2009 12:35 AM PDT

I have Auslogics Boost Speed. I downloaded the trial version of PerfectDisk. After I run PerfectDisk, if I check BoostSpeed it tells me my disk needs defragmentaion. My computer seems to be faster after using Perfect Disk. Is there a defragmentaion program that is better than these two?

It is a matter of opinion...

I prefer Diskeeper, with a much older version being the basis of Windows' defragmenter. Diskeeper's marketing dept claims it is better than PerfectDisk. Of course, PerfeckDisk's marketing dept claims it is better than Diskeeper. There are no conclusive results from independent, unbiased third parties so it is hard to tell which is correct. Regardless, most would agree there isn't a significant difference, so either one would be sufficient. Just do not defragment excessively, as that can wear out a hard drive.

Hope this helps,

Same here.

I prefer Diskeeper too. I am using DK 2009 pro on XP Pro SP3 machines currently, and it works flawlessly.

Best Defrag Progam?

It's a question that has millions of answers--and all of them end up leaving you confused.

I find that using something that both defrags and optimizes helps some. There are both free and paid software to do this.

Auslogics had one, but their new version does not optimize unless you pay for it.

So, I use Auslaogics for defrag only. And, I have a really old version of System Suite to optimize. Using them together seems to help my computer.

Oh. XP with SP3.

Auslogics is OK, but that's about it. For my and my wife's computers, I have a 3-machine license for Diskeeper which is significantly better than any of the free defragmenters if you need it. That last phrase, "if you need it", is crucial. Most casual Windows users can get along quite nicely without something as powerful as Diskeeper.

In the realm of free defrgmenters, I recommend IObit Smart Defrag. It's faster and more effective than Auslogics and Glary (I never tried PerfectDisk).

As has been previously mentioned in the discussion on registry cleaners, take their "reports" of what's wrong and well they can, or have, cleaned it up with a grain of salt - it's all marketing. The only thing that's significant is whether you notice any speed improvement after using it.

Perfect Disk
by mikebliv / June 26, 2009 6:36 PM PDT

I have used Perfect Disk before after finding the explanations on their defragmentation logic convincing (free space optimization). This was a few years ago and the equivalent DisKeeper did not have a similar feature at the time (They to have it now). JKDefrag was also a very good free alternative. Here's a good defrag comparison site (http://donnedwards.openaccess.co.za/2007/06/great-defrag-shootout-all.html). Bear in mind that Windows Vista and 7 have a defragger built-in, with 7 maybe being a bit more intelligent too (e.g. there is diminishing returns as a fragment gets larger, the break even point being at 64Mb according to http://blogs.msdn.com/e7/archive/2009/01/25/disk-defragmentation-background-and-engineering-the-windows-7-improvements.aspx). I don't trust XP's defragger but I won't bother for Win7.
