Turn off Windows write-cache buffer flushing

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?

 

1) Unforeseen power outage is always possible (BSOD, for example), even with a notebook.

2) It doesn't.


Experience with many varied systems show that they are the fastest (snappiest) without checking that box. With it checked, the user experience becomes molasses-like - even just browsing, for example.

I don't know/care about better benchmarks. But I do know that checking that box leads to a much slower O/S experience from a users perspective. Even if the raw performance was better (which it isn't in my past tests), it feels slower to the user - so a benefit, it isn't.

 

Reason #1... Leaving that unchecked is always wise on an overclocked benching machine. Data loss can be frequent when you are pushing the envelope on stability and have write cache buffer flushing disabled. While I do care about benchmarks, I don't like file corruption and data loss in the event of an unexpected shutdown, so I leave it unchecked for that reason. (Yes, I have experienced that problem with it disabled. I also back up files I don't want to lose for the same reason.)

 

Yes that's what a guy on OC forums suggested he said the small gain in speed is not worth the risk of corrupting data. Just wanted to confirm from the PROs here.

Cheers

 

With my DBAD RAID setup I always disable it. As some have mentioned, with it enabled you will experience more slowdown and the extra writes it makes to write periodic cache data to your drive is more hurt than harm to a SSD. If speed is important to you, you're better off risking it being turned off for the huge boost in performance.
