do you guys defrag your hd? if so, do you notice any benefits or is it just psychological?
It's just about all placebo except in corner cases. If you're using Vista it's already doing background defrags so just let it do it's thing.
There stupid, Test are total flaw and as anyone knows 30seconds added to start up is a long time and shut down isnt as important but still 10 seconds means alot for reboots
Most benchmarks are flawed in one way or another, it's just the nature of the beast. There's no good way to automatically benchmark real world usage.
One problem is they ghosted which also reproduces the same fragmented FAT.
If it does, your imaging tool is broken.
They needed to use the MFG copy software, A File copy image will produce a clean MSF/FAT.
No, any imaging tool that understands the filesystem being used will give you a defragmented image.
Ive hear but as rumor that Vista defrag leaves little to be desired, But Im sure somone could que in on that wether 3rd party might be better.
Lots of people say that but no one has been able to produce numbers to back it up.
Defrag makes a difference but it can be minimal or great change.
As Spindle drives have changed and evolved over the years different set ups can produce considerable differences in speed and change from file fragmentation.
The difference is almost always unnoticable. There's very few cases where it would make a real difference.
This even goes with any OS (Yes Nix also), Theres are changes that accure durring clean ups and defrag that alter the statistics of how a OS handles file access.
But most unix filesystem drivers are smart about file allocation so there's very little fragmentation to begin with, not that it makes much of a difference.
An eg. I can give is a 250Gig drive used for say 5 years without defrag, If benched then defraged then benched then imaged off formated and imaged back again, Benched will produce 3 different benchmarks, Why?, Well for one the Files are located in different spots on the spindle, The other is that the MFS (FAT or what ever the initials elude me at the moment of writing) has also changed and in size and fragmentation.
The MFT (assuming NTFS) should be the same size in all 3 cases because it's size is based off of a percentage of the drive size. Sure you can manually force it to be a different size but we're assuming you didn't do that. As long as you're not doing anything else while running the benchmark the numbers of all 3 runes should be very similar.
This is also more noticable in OS that any kind FAT over BAM as its a redundancy of look up tables that become fragmented.
No, FAT or MFT fragmentation has little to no affect because they're so clustered together anyway.
I think I will reproduce there test, But Im going to have to leave part of it out as I defrag often because I can tell when even my page file has fragmented to much.
But I will try both File image and ghosting and post up my findings
Pagefile fragmentation is irrelevant because that file is accessed randomly anyway and almost always amongst a lot of other paging activity. Go ahead give it a try if you like but all you'll really find is that getting an accurate benchmark is very difficult.
