Mr. Anderson

I setup a RAID 0 with two Raptor on ICHR5 on my Asus P4C800-E.

May be this has been asked before but I can't find it...

Is there any need to defrag a RAID 0 array? (Windows XP)

Thanks

Mr. Anderson

hmmm, just find it :-)

"You never ever have to defragment a RAID0 array, preformance does not
degrade with file fragmentation as with stand-alone drives and the disk
contens take much more time to fragment as much as in stand-alone drives."

Any other advice?

Thanks

Where did you find that? That's not true. As far as Windows is
concerned, it's just one big drive. It may not be quite as affected by
fragmentation as a single drive, but it WILL be affected if it gets bad
enough.

NTFS fragments and is affected by it, no matter what the underlying
hardware is. Even a Flash drive should show degradation. NTFS is a bit
less sensitive to it than FAT, and faster hardware makes it less
noticeable, but it STILL happens.

I have a single 120G drive in my system, partitioned 10/110 (cloned
when replacing a 40G partitioned 10/30). It originally came with the
full 40G as FAT32, and ended up with 512 byte clusters when converted to
NTFS. I ended up repartitioning it because 40G of 0.5K clusters is SLOW.
Even reduced to 10G, I need to defrag every day or so because several
programs, especially my newsreader, get noticeably slow.

That's not true.

Like the 3 minute difference between posts wasn't enough of a clue.
 
Thanks Andrew,

I should add that for basic use, the defrag built into Win2K and XP (a
cut-down version of Diskeeper) is fine. Depending on what you use the
computer for, once a week or so will be more than enough. You cannot
schedule the built-in defrag to run automatically, so it's one of those
things you have to remember to do. The main advantage of 3rd party
defraggers are speed and scheduling. Other features like ordering files
in a particular way are more hype than reality.

And you are doing such a fine job of ignoring me when 95% of this message is geared to me, rather than to Andrew.
 
Diskeeper really is a cool program. When I heard about Diskeeper, it
somehow rubbed me the wrong way and I was very much against its use. I
guess it could have been the amazing claims made by the manufacturer, and
the fact that I have not once seen a problem that was cured by a disk
defragging. But I have to say, after using Diskeeper, I have become a big
fan. It sounds funny to say, but my life feels more satisfying knowing my
hard drives are defragged and because it happens automatically at midnight
every night, I never have to think about it.
