I used to love PCMark 05 before the cheats wrecked it.
1 SSD wont cut it 2 in raid 0 will improve your score big time 4 SSD's will be even better. Small stripe size is desirable i.e. 16kb
Frank use to run Irams for the drive tests I used to use Acards both are Dynamic ram Disks using memory sticks as hard drives.
With any raided setup remember to keep the XP startup test below 220Mbs.
Transparent Windows Test use Bobs tweak.
Click on the settings tab in PCmark 05 we use that window to check that the tweak has taken.
Right click on the desktop \ properties \ change desktop to windows classic apply and go back to the desktop.
Hold down window key and press L key to log off click your name to log back on now the settings window should be shaded grey. If so the tweak has taken.
Change the desktop back to the windows 7 theme.
Close the settings tab and run the benchmark.
You can change the wallpaper to what you want after the bench has run.
IE9 is the browser to use lower all protections and in advanced settings uncheck everything except the last 2 at the bottom.
I would have to have IE9 open in front of me to explain it better.
You also need the results text window open so you can see all tests Program files\Futuremark\PCMark05\Results.txt
Here is my Q6600 sub and a pic of the Acards.
