Leave the SSD as unallocated space, this means no partitions. You may also shrink the partition on your boot drive just around 200 MB. I recommend uninstalling the current version of Intel® Rapid Storage Technology version and installing v.12.9.
1) SSD as unallocated space (it is the case, see disque 2
2) shrink the partition on boot drive around 200 MB: the System Reserved space on disque 0 is 100 MB so less than 200 MB
3) The driver vesrion is now V12.9
BUT STILL NOT WORKING
I did a fresk installation of windows 7 on a small raid 1 (75 GB) and installed the SSD and RST (last version) and, in this case,I was able to accelerate the volume 0.
What's wrong in my first configuration which not allow me to use acceleration ?
