Raid 0 performance dropping with time, why?

[Mr.Rotory]

The first time I installed my system with my new mobo running raid 0, I ran pcmark2002 and scored 1950 that was about 2 months ago. About a month ago I ran it again and got 1800, now I run it and only get 1550? Any idea why?

First, take all benchmarks with a grain of salt. Do you regularly defrag? If so with what? The speed degredation could be due to fragmentation, bad sectors etc. New installs always seem to run fastest.

Spyware and Adware has been known to slowdown the system if you let it pile up.

I would defrag, run ad-aware or a like program, and do a a virus scan. Also, if you system has been up for an obscene amount of time (2+ months) I would suggest rebooting.

I forgot about that lol. There are some preograms out there that clean out the ram.

Every few days you should clean out the cache, temp internet files, history. I do it a few times a day:D Every few hours the cache fills up 12MB surfing around, it happens to me anyway.

It's a fact that XP updates slowdown the system; there is a slowdown fix.

[Mr.Rotory]

I've just refraged, I dont have any spyware, or atleast I run search and destroy to make sure, plus i am not using any file sharing program, I dont have anything on my system that is eligal, all is registered, no mp3's, very clean. So other then my ATI icon logitech/mouse software and sygate firewall with plextor tools are working, if fact that pretty much all the installs on my comp. I do need to restart and clean out the cache.




P.S. I ran defrag using windows tools, after this I ran PCmark 2002 and my score is only at 1580 :(

[Mr.Rotory]

OMG!!! I just rebooted after cleaning out the c: d: e: drive's (i have 3) and now I scored even less,...................1540!!! anybody know why?



P.S. I did have all the start up stuff running, which isnt much but i guess it could have possibly effected the hd score but still 5 things and the AIW bar isnt much.

[Mr.Rotory]

This is getting to be scary, ran it again, this time with everything off and now i'm at 1525!

[NoteUser]

I don't know how you ended up with so many partitions by just defraging and cleaning out the system, imposible.

Maybe you should consider a fresh install. The worst thing that could happen is if the drives are breaking down useless.

[Mr.Rotory]

I accually have 2 120 gig hard drives, split into 9(c drive) gig 36(d drive) gig and the rest to e drive.

[NoteUser]

If you had less partitions it would be faster but that doesn't explain the speed drop if it was originally configured that way.

I'm stumped. If you are running XP and you update it regularly you should be ok assuming you installed the XP slowdown fix.

[Mr.Rotory]

Is the slow down fix on their regular update site?

[NoteUser]

It should be.

Also, simply having data on the drive tends to decrease benchmark scores. On a fresh install, you'll have a gig or two used. Running a benchmark lets it benchmark the fast area of the drive since nothing is there. As time goes on and data fills up the drive, the benchmark is forced to preform it's read/write tests on slower areas of the drive. Benchmark software will not touch your data, so filling the drive forces it to use slower and slower areas of the disk.
