I was Defragmenting my PC Yesterday as i installed 157GB worth of Games.
only to be shocked in Windows 7 defragment them in around 7 minutes.
To me this seems to fast don't you think?

Do you think Windows 7 Does a good Job?
Have you noticed this?
What are your thoughts on This?

i got a feeling FireWizard will have some words of wisdom.:D
 
Win 7 schedules itself to defrag in the background, so it is constantly doing little bits and pieces to minise fragmentation.
A swift run defrag would suggest it hasn't been long since it did the system itself.
 
IIRC Windows 7 defrag ignores file chunks over 64MB in size, as consolidating them won't lead to any significant performance improvement. If the bulk of your 157GB fell into this category it will probably have been left alone.
 
do you think its worth installing perfect disk then? as i have a license from my vista install thats now on win7 :)
 
I'd not bother. Fragmentation on NTFS isn't an issue. Never really has been, especially since Vista added automatically scheduled defrags...

Third party defraggers all use the same API as the Microsoft one. All that is different is what algorithm they use. Generally they operate a far more aggressive algorithm. But the law of diminishing returns applies. As already said, defragmenting large files is a largely pointless exercise. Likewise, defragging files that are only ever written to and not really read that often (i.e. log files) is again pretty pointless.

The best thing you can do to optimise a disk partition is to decide what type of files you intend to store on it and then modify the cluster/block size when you format. If the partition will be used for storing very large files >100MB or even >4GB then you should use a large block size... maybe 32KB or 64KB. Whereas if the partition is for your Windows install then the default block size of 4KB is far better.

If you get your block size right from the get-go, this will allow NTFS' file allocation algorithms to work better and make more accurate real-time decisions when it comes to deciding whether or not to maintain a contiguous file or to fragment it.

Agree with all the above, third-party defraggers are completely unnecessary unless they can actually make your PC perform better than the inbuilt tools, rather than just make pretty patterns out of coloured squares (I'll be asking for citations if anyone claims they can...) :)
