I would like to use 32GB mSATA SSD in 14z 5423 as normal data disk

I have a new Inspiration 14z 5423 and it comes with 500GB HDD and a 32GB mSATA SSD for acceleration. I plan to replace the HDD with a SSD so I don't need the acceleration any more.

But I don't know how to disable the acceleration and use the 32GB SSD as normal data storage.

Any help in appreciated.
