Windows 10: Disable Filesystem Cache/File Direct write to Disk

Hi All,I am doing a testing inside diskSSD FW level. Whenever the files are copy/written from the windows it doesn't come to disk immediately, it cached the file write operation and written the disk as bulk. Eg: I am trying write 5000 fileseach file 4K size, As file size is very small it cache all the files and dump 5000 files at one burst. There are flag FILE_FLAG_NO_BUFFERING/FILE_FLAG_WRITE_THROUGH but this can only using CreateFile API's. I want this solution as generic file manager like even windows file copy must come to the disk directly.I have disabled policy->Write-Caching

Disable Disk Write Caching on SSD in Windows 10

Not true.

Write caching is there to defer disk writes until later.

Why write blocks to disk if a program might change that block, forcing it to be written to disk yet again?
Why write blocks to disk now if the filesystem is busy with other tasks?
Just cache the blocks.
And keep them cached so that if they're needed again they can be read from cache rather than from disk.

Caching reduces the overhead. But it makes the system vulnerable to data loss if power is abruptly lost before the cached blocks can be written to disk.

The risk is small, so we almost always keep disk caching turned on.

 

Enable or Disable Disk Write Caching in Windows 10


hi Brink,

I can't enable write caching on my Micro SD card 128 GB on Win 10 Surface Pro 2 ?

On Win 7 I was able and works ok.

If I try enable in device manager I get windows error - could not change write caching settings on this device...

Something wrong with WIN 10. I keep my Outlook files on my SD card and always freeze up my outlook 2013 after some time and I must restart computer.

thanks in advance with expert help
