Why is my hard drive performance so bad in Windows 7?

I have about 5 TB in HDD space with about 3 TB in a RAID 0 setup.

Under Vista, my HDD performance was very good.

Now, my HDD performance is horrible. I'm not talking about stats, I mean from a real world standpoint. Whenever I open Firefox, it takes about 45 secs. If I have other programs running and try to open up something simultaneously I will get a "Not Responding" warning. It's gotten to the point where my system is ridiculously slow.

Is there some setting that I need to change? It sounds like something is not set correctly.

Thanks,

DD
 
After fresh install of Windows 7, I, too, experienced a very slow HDD performance problem. I could notice it even without using any benchmark softwares. Especially, my HDD made more seeking noises. It was more evident When watching videos; skipping timeframe was slower and everytime I moved timeframe slider, I could hear seeking noises every single time...

I had latest Intel Chipset driver installed and all the cache features were turned on under Windows' device manger control panel.

What fixed it was installing new Intel Rapid Storage Tech. software formerly known as Matrix Strorage Manager although I don't have RAID setup.

Below is the link for the software. Try it and let me know if it fixes the problem you're having. I'm not sure if your problem is same as mine as yours sound like dying HDD problem but give it a try anyway.

Thanks!

I'll give it a try. I don't think its a dying HDD since all of my HDDs seem to be affected. My problem seems a bit different from yours in that its the opening of programs and files that take a long time. It also doesn't seem to like multitasking as having 2 different HDD using programs slows everything to a crawl or stops completely. I didn't have this problem before I upgraded to Win 7.

The Intel rapid storage driver is still in beta stage and has not been officially released.
 
Is this issue Firefox exclusive? It could possibly be a chipset/storage driver or maybe a botched upgrade. Open the Resource Monitor to see what's using disk time, maybe the Performance Monitor if you know your stuff.
 
do you have backup running in the background?...
it schedules itself and will automatically run when/if you miss the schedule.

just disable it if it is...

These are exactly the kind of issues I have been having. Post the solution that worked for you, if you find it, thanks.
 
I recently installed a fresh version of W2K and had the same issues.

Make sure DMA is enabled?

Im going W7 tonight, hopefully a good install from 32 bit to 64.
