First,The Results WEI score, left side is SSD :)Crystal Disk MarkATTO Disk BenchmarkBoot time (sorry forgot to screenshot the before, it was 82 seconds) :And now, i'll list the operations i've done to optimize my new SSD's performance.I won't go into the reasoning for those steps, they've been discussed time and time again, this post is just to organize the steps to execute them.So here we go:1. Reinstall windows from scratch.2. Installing all the drivers, chipset first and then the rest with restarts in between.3. move c:users directory from my SSD to the data drive using symbolic link1. Booted with windows 7 Media, chose repair windows2. choose command prompt3. copy users to hdd (when booting like that my C drive became E and D remained) robocopy "E:Users" "D:Users" /mir /xj /e4. rmdir e:users /Q /S (you might want to just rename it in case there are porblems)5. mklink /J e:users d:users (when booting like that my C drive became E and D remained)restart and you should see your users directory on the data driveThen run services.msc to disable the following services:1. Disk Defragmenter2. Superfetch3. Windows SearchAlternatively you can start an elevated command prompt and run the following three commandssc config defragsvc start= disabledsc config SysMain start= disabledsc config WSearch start= disabledOUTPUT FOR EACH SHOULD BE : [SC] ChangeServiceConfig SUCCESSNext, Open my computer, right click on the SSD drive choose properties and remove the checkbox from "Allow files from this drive to have contents indexed..." press Ok, and then choose the recursive option, OK and wait for it to finish.Next i enabled write caching on the SSD drive, for that, we need to go to device manager. (Right click on my computer, Manage and choose device manager). There we need to expand the "Disk Drives" section and select the Intel SSD... device, and right click properties on it, in a window that opens choose policies tab and check the second checkbox that says "Turn on windows write cache buffer..."Disable superfetch and prefetch:run regedit go to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetContro lSession ManagerMemory ManagementPrefetchParametersSet 0 onEnablePrefetcherEnableSuperfetchDisable Hibernate :start an elevated command prompt (start, in the search box write cmd, right click the result and select run as administrator)C:Windowssystem32>powercfg -h offFinally disable system restore:Right click on Computer, Properties, Advanced System Settings, select system protection tab, choose the SSD drive (usually C),press Configure and select Turn Off System Protection.

I decided i'd compare the performance of two famous tweaks done to the OS to improve SSD performance. Those tweaks became famous due to the previous generation of laptop chipsets that were limiting SSD performance to preserve battery life. I'll be comparing a Vertex 3 240GB SSD on SATA III (6 GB/s) interface inside the Alienware M17x-R3. (Note : Even though the tests were made on the M17x-R3 the results are almost identical with the M18x, since they use the same chipset. I confirmed it with [MENTION=5]Brian K.[/MENTION]) I measured the performance with CrystalDiskmark in three cases. Default install without any tweaks JJB processor power state tweaks via windows power management IntelPPM tweak, brought to us by our own @StamatisX which for previous chipset models brought the best performance increase. So without further ado, here are the results. As you can see, no much gain there. Here's another look at the results, the graphs are improvement in percents over the default result in read and and write. We can see that the best performance increase is achieved with the intelPPM tweak, at 4K reads. Rest of the improvements are quite negligible - under 5% in in some cases i even saw a decreased performance. One note about intelPPM, it does seem to disable turbo boost on non-extreme CPUs so, it's quite unusable for most of us. You guys can draw your own conclusions of course, but for me, those tweaks are not worth the trouble. Another conclusion is that the current HM67 chipset does not seem to suffer from bad SSD performance, at least not as much as the previous chipset was. Opinions ?
