I added a 2nd 320 GB HD to the original 320 GB HD. I used Intel Matrix Storage 6.0 to set up the raid 0 (striping) after the two hour migration I was reset the computer. after the reboot there was a balloon on the task bar "new hardware found" for the array. the I went to pcpitstop.com for a benchmark test. I got about twice the transfer speed. Then I when to my computer, under Hard disk drives it show local disk 293 GB total space and 11.4 GB free space, those are the same stats from before. I checked Intel matrix storage it said:
