How to limit the disk cache memory buffer size? RRS feed

  • Question

  • Hi,

    I would like to limit the amount of OS memory used for the disk cache. How this can be done? Something like this:

    MaximumDiskCacheSize=100M

     

    Thank you very much in advance,

    Alexander

  • Hello,

    As far as a know, disk cache is memory physically found on the hard drive itself. Depending on your model drive, it may have different size disk cache. Turning it off is usually to disable write caching to prevent corruped data if your pc is prone to power outages or freeze-ups.

    You can disable write caching in Windos from the disk properties in the device manager. Right click on the disk, select properties and it's under the policies tab. You can also look in the disk controller BIOS or the system BIOS for more cache settings there.

  • No, I don't want to touch the _physical_ disk cache size (on the hard drive). I want to limit the amount of memory used by windows for disk cache. BTW, this is on Windows 2008 server...
