Turn off Windows write-cache buffer flushing

[Berryracer]

In my SanDish Dasboard, it recommends to enable "Turn off Windows write-cache buffer flushing" for better benchmarks.

1) Is this also a good tweak outside of benchmarks? like from my day to day use? I am on a laptop so a power outage is not possible as it has a battery

2) how does this improve performance from a technical perspective?
