Windows 7 defrag — optimization missing
In the continuing story of what is missing from the Windows 7 defrag tool, today I’ll touch on drive optimization. PerfectDisk’s patented file placement strategy is based on file modification activity. This strategy groups files with similar modification patterns together, in a single pass. Since the rarely modified files are typically unchanged and grouped together, PerfectDisk is not required to use resources to process them during a subsequent defrag. This saves system resources and improves speed, as the drive is in essence “shrunk.”
The recently modified files are adjacent to the contiguous free space. If one of these files grows, the fragment will be created in one piece from the contiguous free space. As a result, fewer defrag passes are actually needed, saving more system resources.
The Windows 7 defragmenter has no file placement strategy whatsoever. Files are defragmented haphazardly with no regard to type and usage pattern. No consideration is made to slow the rate of fragmentation build up. No attempt is made to improve the speed of subsequent defragmentation passes in order to reduce resource impact, and no attempt is made to consolidate free space for the best possible write performance. As a result, the Windows 7 disk defragmenter will never provide the same level of performance and resource optimization that PerfectDisk does.
Unlucky 7.

Ithought I would ask you because you may know How does 32bit vs 64bit OS effect these products?

Hi Ric,
Thanks for the comment. Here is a link to PerfectDisk 10 Pro versus one of the products you mention: http://www.perfectdisk.com/products/home-perfectdisk10-professional/learn-more. You can also see PerfectDisk 10 Home on the web site. PerfectDIsk runs fine on both 32-bit and 64-bit.
Thanks,

Windows 7 is much better than Windows Vista when it comes to performance. i like Windows 7 just like Windows XP
Hi Harry,
Thanks for the comment. Windows 7 is pretty nice - I’m with you on your comparison to Vista!
Thanks,
Joe
We agree—while Windows’ built-in disk defragmenter does an okay job, it really isn’t sufficient by itself. This post offers some steps for choosing the right defragmenter for your disk: http://bit.ly/QzutN.
Hi TuneUp,
Glad you agree. Interesting post, although it leaves out my personal favorite defragger, and the only one that Microsoft has certified for Windows 7…:)
Thanks,
Joe
Hi Joe -
well, maybe “your favorite one” will need to looked at more closely and added to the list then.
Hi TuneUp - that would be nice!
Thanks,
Joe
