I have a macpro 1.1 2.66 Ghz, with 16 gigs ram, ati 5770, 250g 500gig hd and a 125 ssd

I just bought a 2.3 macbook pro and dropped in 16 gig ram and a Momentus XT Solid State Hybrid Hard Disk Drive 750 gig 7200 rpm that has a 8 gig sad

It makes my macpro look real slow even when I run on the sad, that being the situation, how can I speed up my macro?

Thanks Gary
