ZZzzzzzZZZZZ Posted August 20, 2009 Author Share Posted August 20, 2009 True, I would have used HD Tune but mine has expired. Can someone else post some screenshots of their benchmark, if possible similar to mine, through the sata controller (speed test) Link to comment Share on other sites More sharing options...
Brandon Live Veteran Posted August 20, 2009 Veteran Share Posted August 20, 2009 Ok here are the results of my benchmark:... You can see the noticeable difference between the two, the burst speed is slighly higher with disabled NCQ. Read above. Those are useless benchmarks, the fact that NCQ has any difference at all is most likely just an inconsistency in the benchmark (did you repeat 3-5 times and average the results? Probably not). However, if you do a random read/write test, you'll certainly find that NCQ helps (unless there's a buggy NCQ implementation in your drive, but that's unlikely).

ViperAFK Posted August 20, 2009 Share Posted August 20, 2009 I don't even know if I have ncq enabled or not, I have no option to turn it on or off like the op in device manager. everest says supported but not enabled on 2/3 of my drives, not sure tat that means (it doesn't say disabled) and ahci is enabled in my bios.

ZZzzzzzZZZZZ Posted August 20, 2009 Author Share Posted August 20, 2009 Yeh When I first got my drive, ran HDD Life and WD Lifeguard from DOS. Drive fully funtional no errors, with a working smart and NCQ Link to comment Share on other sites More sharing options...
neufuse Veteran Posted August 20, 2009 Veteran Share Posted August 20, 2009 If you have an SSD, the best thing you can do is make sure you have the latest firmware. Other than that, just leave the defaults alone - they're carefully tuned to balance the most important performance aspects (sequential read/write speeds aren't everything, it's random mixed I/O more than anything that causes hangs or other responsiveness issues - caching and NCQ help this). where in the world do we get latest firmware for SSD's anyways? I have two that everyone said upadate your firmware for and never could I find a place to (I have patriot memory warp v2 64GB SSD's) Link to comment Share on other sites More sharing options...
morphen Posted August 20, 2009 Share Posted August 20, 2009 Another tip is to disable NCQ on SATA Controller!! why do people insist on turning of the functions that give them better performance? What is NCQ? NCQ is the acronym for Native Command Queuing. NCQ is a feature of SATA-II. NCQ was not supported in SATA-I. Without NCQ, commands are performed by the disk in the order in which they are received. If the commands are reads and writes of data scattered randomly across the disk, a lot of time can be wasted on long seeks (mechanically moving the head long distances) between successive read/write operations. This is particularly the case in a multi-tasking system where many tasks are accessing the disk and the disk is heavily fragmented. With NCQ, SATA-II drives will use an algorithm to determine the most efficient order in which to perform the read/write operations. The algorithm will reduce or eliminate the long seeks. This will reduce the overall time spent on seeking, which is the slowest operation a disk can perform. Yes, the operations will be performed sometimes out of order, and yes, sometimes a task will wait longer than it might otherwise have waited without NCQ, because NCQ lets a different task get its' data ahead of schedule. But the overall reduction in mechanical re-positioning time can be significant and overall system performance is often substantially improved with NCQ.

ViperAFK Posted August 20, 2009 Share Posted August 20, 2009 How can I tell if I have NCQ enabled? the device manager doesn't show it anywhere. Everest says "supported" but next to other hdd features it says "supported, enabled" or "supported, disabled" so I don't know what thats supposed to mean if it says neither. I have AHCI enabled in the bios and I know its working, my drives show up in the safely remove hardware ect... Link to comment Share on other sites More sharing options...
ZZzzzzzZZZZZ Posted August 20, 2009 Author Share Posted August 20, 2009 You be able to tell Go to ATA/ATAPI CONTROLLERS and select your sata controller. As you can see from the picture I have Nvidia, you maye have intel/AMD/VIA Link to comment Share on other sites More sharing options...
ViperAFK Posted August 20, 2009 Share Posted August 20, 2009 I have done that but my controller doesn't show anything about NCQ like yours. neither do any of the channels. I do have an AMD chipset. Link to comment Share on other sites More sharing options...
fhpuqrgrpgvirzhpujbj Posted August 20, 2009 Share Posted August 20, 2009 Ok guys, good speed tweak here. Don't turn your computer on. You'll turn it off eventually anyway, so lets just skip the middle step to save time. Link to comment Share on other sites More sharing options...
Udedenkz Posted August 21, 2009 Share Posted August 21, 2009 where in the world do we get latest firmware for SSD's anyways? I have two that everyone said upadate your firmware for and never could I find a place to (I have patriot memory warp v2 64GB SSD's) I don't think there is any firmware for that - I have that same SSD and I looked before. There is really nothing you can do to speed up reads, but you can speed up writes and make it get stuck less. Link to comment Share on other sites More sharing options...
Mega Goatlord Posted August 21, 2009 Share Posted August 21, 2009 why do people insist on turning of the functions that give them better performance? Because many people, on this site especially, seem to think they know a lot more than they actually do. It's part of the learning process though, thinking all these tweaks actually do anything. They'll learn in time. Link to comment Share on other sites More sharing options...

Jimbo1234 Posted January 25, 2010 Share Posted January 25, 2010 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. That doesn't help as much as disabling the cache flushing. I was using a pair of Velociraptors (10,000 RPM) in RAID 1 (mirroring). With the cache flushing check mark enabled, my Autodesk Inventor 2009 assembly load times decreased by a factor of 2 even with an already fast drive. And this time is measured in minutes for large assemblies. A raptor with the cache flushing disabled is faster than a velociraptor having it enabled. There is big difference in the performance of those drives with all settings being equal, and using the right settings definitely helps. So don't speculate, use real world data. There is a significant speed increase in certain situations. Adding exceptions to SEP11 to prevent scanning of CAD files decreased the load times by another factor of 2. Funny but it wont even allow me to tick those boxes <img src="https://cdn.neowin.com/forum/uploads/style_emoticons/<#EMO_DIR#>/tongue.gif" style="vertical-align:middle" emoid=":p" border="0" alt="tongue.gif" /> If you are using certain RAID controllers you may need to do it through the RAID software. For example, the Intel Matrix Storage console. Link to comment Share on other sites More sharing options...
