So last night, I followed the directions at http://drnathan.teamhackaday.com/20...ntel-ich-raid-after-installing-windows-vista/ to set up 2 Intel 80gb SSDs in Raid0. I had my OS and apps installed on one of these drives already. Thing is, my CrystalDiskMark scores are 2-3x faster now in raid than with the single drive and my performance rating went from 7.5 to 7.9 but Windows 7 still shows my primary drive as 70 odd gb large, instead of the ~149gb it should be. Am I missing something here or is there a way to have Win7 display the full capacity?
 
if i recal raid 0 sees it as one drive. your putting date on each drive so you dont have combined drives of 160 or so gig.
 
You are not seeing the full size because your partition size is set to the original size of your Win7 install, which is 80gb. The instructions on the site you listed is for converting a single drive to Raid1. Which isn't an issue because it will mirror the drive. You're basically going to need to reinstall W7.
 
The RAID bios utility says I have a volume 149gb large that is raid0. I don't think there is a speed increase in r/w as I have seen with my CrystalDiskMark benches
 
Which is correct. The volume is correctly reported as 149Gb, but the partition is still the same size as before. You really do need to reinstall with the raid properly setup. Unless there is a partition utility that can allow you to change the partition size.
 
I'll try to see if Win7 can resize the partition when I get home from work. Both drives show up in the same "line" in disk mgmt, but my 2nd ssd was at first unallocated space.
 


there's no option when i right click to extend the volume. i can however convert to dynamic disk...
 
nevermind. just fixed my own problem. i deleted the "new volume" volume shown above and extended c: into it. it now shows as 148gb total wooo
