ZZzzzzzZZZZZ Posted August 19, 2009 Share Posted August 19, 2009 Open Device Manager, select your Hard Drive Properties. Now select policies tab. Ensure you ahve both of these ticked Once done, click ok to save changes You will notice an instant speed boost Another tip is to disable NCQ on SATA Controller!!

Brian M. Veteran Posted August 19, 2009 Veteran Share Posted August 19, 2009 It may increase system performance, but it will increase your chances of losing data should you have a power outage. Unless you have a reliable UPS, use with caution. Link to comment Share on other sites More sharing options...
ZZzzzzzZZZZZ Posted August 19, 2009 Author Share Posted August 19, 2009 Yeh true, But in UK we hardly have power outages, also forgot to mention laptop users should not really apply this tweak Link to comment Share on other sites More sharing options...
Ridlas Posted August 19, 2009 Share Posted August 19, 2009 I'm sure as crap not doing that :o We have to many power outages around here. Link to comment Share on other sites More sharing options...
AaronMT Posted August 19, 2009 Share Posted August 19, 2009 This is not a must have tweak nor will it optimize any hard drive speed. This thread should be closed. Link to comment Share on other sites More sharing options...
Zoom7000 Posted August 19, 2009 Share Posted August 19, 2009 Yeh true,But in UK we hardly have power outages, also forgot to mention laptop users should not really apply this tweak Heh! I live in London (in the Olympic Borough!) and you should see the fluctuations we get. I've complained to EDF to fix their substation for months!

agreenbhm Posted August 19, 2009 Share Posted August 19, 2009 I'll give this a shot on my laptop (which I use plugged in ALWAYS). Essentially it's a desktop with a built-in UPS. Link to comment Share on other sites More sharing options...
Scorbing Posted August 19, 2009 Share Posted August 19, 2009 This tweak is B.S. I see no increase in speed whatsoever. Link to comment Share on other sites More sharing options...

boogerjones Posted August 19, 2009 Share Posted August 19, 2009 Yeah, this is definitely BS. Mulkman, you should go work for one of the companies that sells junk software advertising instant PC fixes. INSTANT SPEED BOOST!! MUST HAVE HD PERFORMANCE TWEAKS!!! GIMME 5 DOLLARS!! NO, WAIT...GIMME $19.95!! Link to comment Share on other sites More sharing options...
The Patri0t Posted August 19, 2009 Share Posted August 19, 2009 I ran HD Tune with the default setting and after selecting Turnoff Buffer Flushing. The result, I see improvement, not very high but its there: Default Turnoff Buffer Flushing Selected I also want to know, when it says there is possibility of corrupting the data/losing the data. It means the data which is currently being written/worked on, correct? For example if there is nothing running except the usual background services and a download manager through which I am downloading some file and there's an outage, highly unlikely since this is a laptop. Then what is going to get lost? The file being downloaded? Is there any fear of a corrupt Windows? Link to comment Share on other sites More sharing options...
KeeperOfThePizza Posted August 19, 2009 Share Posted August 19, 2009 As most people have said here.. I would advise NOT to do that. If your computer locks up, You lose power... etc.. It will leave you at a much higher chance of losing data and corrupting your windows install. So if you've selected that.... The performance increase is hardly worth the risk.

This is a "GREAT" tweak for those that have (which I assume most have) a UPC. I've noticed my overall benchmarks, and hard drive bench marks go up with using this tweak....and have used it since I was using Vista. Link to comment Share on other sites More sharing options...

Yes, If you do not shut down properly there is always a risk of Data loss. Link to comment Share on other sites More sharing options...
C_Guy Posted August 19, 2009 Share Posted August 19, 2009 Uhhh... Write-caching is not a feature of Windows 7, it has been around since XP, probably earlier than that. If you want a noticable HDD improvement, upgrade to a 10,000 RPM drive. Link to comment Share on other sites More sharing options...
Pharos Posted August 19, 2009 Share Posted August 19, 2009 I use this tweak for years, and never had any problems with data corruption, even though I've experienced a lot of power outages. Hell, I used to even do a hard shutdown of my system because Vista would take too long :p . I guess I'm lucky?! Link to comment Share on other sites More sharing options...

Nagisan Posted August 19, 2009 Share Posted August 19, 2009 Not sure exactly how relevant it is but I actually get better performance with this setting DISABLED on my SSD. Now, my SSD is an older edition (OCZ Apex) so it has no built-in cache, but I ran with these settings enabled on a fresh install of W7 Ultimate RTM and had a few performance issues (as well as WEI rating my SSD at 5.9). Upon installing W7 Professional I disabled this option completely, my SSD shot up to 6.7 in WEI, and I have not see any performance issues I had when I had the option enabled.

ZZzzzzzZZZZZ Posted August 19, 2009 Author Share Posted August 19, 2009 I can assure you this tweak does work, maybe after retstart. I will post some screenshots on benchmark tommorrow.

Raa Posted August 19, 2009 Share Posted August 19, 2009 I use this "tweak" on my server (With UPS), but I don't use it on my desktop PC (with 10k RPM HDD) :p Link to comment Share on other sites More sharing options...
Brandon Live Veteran Posted August 19, 2009 Veteran Share Posted August 19, 2009 Do not do any of these "tweaks." Some of them, in certain scenarios, can artifically inflate synthetic benchmark numbers. But you will actually *hinder* real world performance if you disable caching or NCQ, or put your data at risk if you disable buffer flushing.
