I've just built a workstation and have Corsair Force GT 3 480 GB. I installed Win 7 Pro x64. When I checked the disk it shows 120 GB is in use yet the actual Windows was much less than that. Around 20 GB I believe... (I can't look right just now)
The missing give and take 100 GB is invisible...
I must also mention that right after the initial install process, right at the first initiation of the Windows while I was naming the 'computer' there was a ten minute electricity cut. (It happens around here now and then!) So when I was back at the saddle I struggled a bit not being sure what was going on, I almost started a new fresh install by mistake and I saw a second partition was about to be created, so I cancelled and reboot the system and continued from where I left off with the first installation..
Thus now I have 120 GB on my 480 GB SSD and there is nothing but the Win 7 Pro x64 which takes all that space I need for my own reasons!
Please tell me this is all wrong and I have to do a new fresh install butu this time with my loyal 2000 AP 'UPS' unit present.. )
Since you have 64gig of ram the page file will be absurdly huge, same goes for the hibernation file.
I suggest manually setting a page file size as well as disabling hibernation.
Instruction on how to do both can be found here: http://www.computing.net/howtos/show/solid-state-drive-...
As well as a few other tweaks.
They suggest disabling the page file completely but i would not recommend that, i usually set it to 2gig with a max of 8gig.
