Unacceptably high disk usage/performance lag Windows 8

Hello SNGX. I've been surfing the forums for the same problem for a while and I just need to present my problem as well. Maybe if we find out what's wrong in every occasion we'll have a lead to the problem. I have a hunch that all this has something to do with Win 8 as well.

I've been using Win7 Ultimate forever without ever experience such problem. I have also been using Win 8.1 for as long as 5 weeks without any problem whatsoever. I was extremely satisfied with my booting times and overall performance.

I am going to begin with a few words about my rig. It's mainly for family use and some gaming. It has a Intel Core 2 Duo @ 3.00GHz, 4GB of ram (3,19GB) all on a Win 8.1 Pro (64-bit naturally).

I also have 2 HDD: C: 149 GB (ATA) and E: 153 GB

Filesystem is on C and I mainly use E for my storage needs. Yesterday, I found out that my game loading times were crazy slow. A quick look at the TaskManager revealed that E (where my gamefiles are stored) Was reporting a 100% Active Time, 0 R/W (or abnormally low) and Avg. Response Times raging from 1000ms to 22000ms (yes... that is 22 thousand). My first thoughts were: "Holy **** it's dying!". I found out I could access small music-image files with no problems, but moving the big backup files from the near death drive to the one that seems to be working would end up just like yours. At the beginning, normal speed for 5-6 seconds, and that's it. The graphs looked exactly like yours, (both the file transfer and the Task Manager ones.

At this point I recall, few days before, I was trying to move a big bulk of files from a LAN Linux PC through samba, and it wouldn't work unless I moved them in small groups. At the time I thought it was a linux smb problem, but now I know the truth.

Browsing through this thread I tinkered the paging setting as someone suggested. I assumed I somewhere screwed up, since now disk C: is showing the same symptoms. I reverted the settings to what they were before I touched them and rebooted several times. Yet the problems persists, now affecting both the general storage disk AND my filesystem disk. Now I am starting to experience some general lagging on normal tasks that would be alright before, with one disk spinning like crazy.

I can't help but worry about this glitch causing physical damage to my disks, since I can hear some high pitch sounds coming from the box.

I am pretty sure this has nothing to do with hardware, since it has been reported on high performance server systems, family PCs, gaming rigs and laptops, all running Win 8 or 8.1.
 
@herku1004 - I don't have any answers on this. Several people with similar (but not identical) symptoms say it is Superfetch. I really didn't think it was in my case, now I'm not so sure because it has been so long since I started this thread and I've kind of forgotten all the details (and I'm too lazy to read through it all again). But since your symptoms seem to be the same as mine, try and disable superfetch completely and see if your problems go away.
 
Hello all!

This laptop with Windows 8 was having the same problem. The HD performance constantly showed that I was around 90-99%, even though the numbers of space used by programs added up to only a tiny fraction of its use.

I was constantly having problems with the computer locking up while loading web pages and while trying to run programs like photoshop. Life was getting VERY tedious. :(

I assumed that this laptop (a refurb) simply needed more RAM, until I noticed the weird HD performance.

After reading the responses here, I Disabled the SuperFetch Service and instantly the problem was fixed!! Thanks guys!!:D(y)

Stupid Windows 8....:mad:
 
With Chrome, I cannot change the location of the browser cache

Actually you can. I've recently moved all my browser cache's over to a RAMDisk, and though Chrome was the least intuitive, it is possible.

Adjust your shortcut with the following flags:
--disk-cache-dir="X:\Path\To\Relocated\Chrome\Cache"

So for example, mine is set as:
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disk-cache-dir="R:\Chrome"

@John C Bell - good to know. I'm not really interested in doing that anymore, it is just a workaround I had done with Opera when I was on a domain a few jobs ago and cache was going to a network drive which was obviously going to be slower than a local. When I had the crazy disk usage problem there was no information on what was causing it on the internet at that time - at least none that I could find. I was looking to see if I could change to get disk activity off the same disk as the OS. Its a non-issue now since we know how to cure the root problem.
 
I've been around the web a few times on this with my Pavilion G7 AMD, did the BIOS updates, etc. and the only thing that works is stopping Superfetch. Turn it back on, disk is up in a couple minutes, turn it back off and usage drops to 0 even as I type this. I've disabled it for the time being.

superfetch is casing lagg issues in SSD. that type of hardrive does not need it. it will in result shorten your SSD life.

There is absolutely nothing in anything I posted that would indicate I was having this issue on a SSD. My screenshots early in the thread clearly show there is not an SSD involved in any way. I have no idea why you quoted me responding to another guy - the other guy also gave no indication of having a SSD, in fact, he specifically stated which HDD he had.

Posts like yours are why people want to disallow guest posting on the forums again.
 
I am nowhere near as PC literate as many of you, but I was having the same problem on an ASUS mechanical hard drives (HDD's?) running Win 8.1, with disk usage always at 90-100% while doing nothing but simple browsing. Constant lagging and complete freezes. Based on previous comments I disabled Superfetch since it seemed like I could reverse that action easily. The computer performance has totally resolved and has worked fine since, with disk usage now regularly at 1-6%, FWIW. Best of luck to all.
 
I have had this problem on win8 and win10. I have searched for months and nothing that I found on the Internet seems to help. I get the same results as you do when copying to a certain hdd. My screenshot would look the same. So if anyone got some news on this, please help.
 
Just a reminder: Win7 was typically installed with legacy MBR while win/8 and onward systems use UEFI
