fusion advice with bootcamp

[gothbiker]

I've a 2011 mac book pro with a 750gb drive, I've replaced the optical drive with a 256gb ssd, which is the best way to make a fusion drive, I've spent a few days reading, but i cant find out which is the best way, i need to keep bootcamp, I'm partly tempted to buy another internal drive and keep the original 750gb just incase i cant restore everything, has anybody else done this? or does somebody know how to do it?
thanks in advance, dave
