I just get a Asus P6Z68-V board.
the caching feature appear to works on my bootable drive, but I'm not able to activate it on a secondary drive.
is it possible to use this feature on another drive than the bootable one?
Indeed, the Intel(R) Smart Response Technology can be used on any drive, however, any given SSD can only accelerate one of the drives on the system. That means that if you have already used the feature on your primary drive, you will not be able to do so on a second disk.
