Having two layers of caching probably won't do anything for you - you can do it, but I doubt you'll see any performance increase.
You could use the mSATA drive as a scratch drive, or get yourself a 120-128GB mSATA SSD (which will probably cost about as much as the SSHD) and install windows there - much faster than even a hybrid drive.
Thanks for responding.
Well at the moment I've only got the mSATA drive and a 120GB hard drive (5400rpm) which I took from an old machine, and getting a 120gb mSATA would cost £30 more and wouldn't give enough space.
Sorry if this sounds a bit stupid, but is a scratch drive the same as a page file? I don't think I've heard that term before
