Is it possible for HD to be a bottleneck?

I have a amd 965 BE x4 processor, 4 gigs of ram and run a win 7 64 bit pro edition. I have an 4 year old 250 gig 8mb cache WD hard drive. My computer has been experiencing lag recently, mostly when im browsing the internet and was wondering if it could be my hard drive. This hasnt happend before so i was wondering what the possible reasons could be. Thanks!

More about bottleneck
  1. Is it a PATA HDD?
    There could be a HDD error or faulty HDD which could cause your system to stick and run every few seconds....
    You need to run a few analyzing programs on the HDD to get the required DATA, it usually doesn't happen unless the HDD is faulty or the Cable has a problem....
  2. On the other hand, even a properly operating HD will bottleneck a system. That's why SSD's are becoming so popular.

    HD's are basically mechanical. Mechanicals are always slower than than electronics.
  3. If the model# is WD2500KS (I have a few of these) then the average throughput of this drive is ~50Mb/s which is kind of slow by today's standards, but it shouldn't necessarily lag unless there is a lot of disk swapping/caching going on at the time.

    If you're using a virus scanner, try temporarily disabling it. It may be scanning files in the background.

    You may also want to try clearing your browser cache. Corrupt files in the cache can make the browser act wonky at times.
  4. Not sure what these terminologies mean. What is PATA and IDE? ALso i use avira free antivirus.
  5. PATA is the Flat grey long cable that we used to have for earlier HDDs it's like a ribbon cable for the Floppy Drive (Parallel ATA) and today we generally use SATA (Serial ATA) thin sleek looking flat cables for connecting the Drives to the Mobo....
  6. SIW says i have a SATA 3. The model number is WD2500AAJS-00VTA0

    i was wondering if this hard drive is a bit out of date and if it would possible cause lag.
    thanks!
  7. There has got to be a mistake :) 4 years ago they didn't have SATA3??
    It must be a simple SATA Drive with the 3GBps thing.

    I still think you need to check the drive for hard errors.... and yes do disable restore point for that drive and the anti virus.... then go ahead and try doing what you do and run a few tests too....
    Post the results....

    Use a utility called Crystal Disk Info.... that's free and will give you a lot of data about the drive and it's life.....
    Post the screenshots here and we'll tell you whats happening.....
  8. You can consider maintenance tools for your PC, once in while the PC needs tuning up.

    I suggest tools like TuneUp Utilities or PC Mechanic.
  9. Technically speaking, yes your hard drive can a huge bottleneck....it is the slowest part of your PC by a long, long way. But, it also depends on what you are doing. Browsing the net is not usually something people would associate with slowdowns caused by your drive. But your internet cache can be huge, a 250gig drive is not that large anymore, and if the drive is like 70% full, and you have a lot of stuff in you temp folders and Internet cache, and IDE to on top of that, yeah you can have problems. Empty your cache, empty your temp folders, and defrag your drive. If it is close to 80% full, you may want to consider an upgrade to a faster/larger/more modern drive.

    here is the result of crystal disk. dont really know what it means. Do i need a new hard drive? thanks

  11. bump :lol:
  12. The first Value itself is pretty high.... the spin up time..... :(
    That should be approximately in the 70-90 range....
    It seems to me that your HDD is going to fail pretty soon, since it's not giving any rotation speed either, it should have been 7200 or 10000 depending on the HDD model.
    High spin up time leads to lags in small files :(
    So yes, it's time to back up your data on this drive and get a new fast HDD....
  13. is there any other reason why the rotation rate isnt showing?

    also i was thinking about this WD black hard drive. what do you guys think?

    btw. i got a 5.9 on WEI for primary disk data transfer rate if that means anything
  14. It's not showing and slowing down itself is the sign of a failing drive.... :)
    That's a good drive......
  15. As long as it is not full or showing lots of errors it is still ok.

    Western Digital Caviar Black WD6401AALS 640GB 7200 RPM 32MB - ok very good HD.
