Hi all

windows write-cache buffer flushing - what isit? and what setting am I best having it on as it contains three settings

In the case of a hard drive, the operating system flushes commands to a disk's on-board cache. That doesn't mean it's safe yet, though. So, it waits for the drive to report back that cached data has been written to the magnetic media. If you're more concerned with performance than the integrity of your data, turning off write-cache buffer flushing skips that extra command to flush the internal RAM buffer.

I only have 2 options as do most, enable or disable, however, and this is where it gets confusing, if you enable write cache buffer flushing, your actually turning it off, as above, turning off write-cache buffer flushing skips that extra command to flush the internal RAM buffer of your disks, making the whole OS a bit quicker.

My guess is you want Data Performance to enable this option.
