Recently installed two X-25M in my old MBP 3.1 Santa Rosa and my new MBP 13.
The thing is screaming fast, even the old MBP 3.1 with SATA-150 is blazing fast. The real life experience is about the same, they boot about the same (15-20 sec) and the programs open immediately. The machines are much cooler and the battery life improves by approx. 30 minutes. The new MPB 3.1 has an advantage with better read performance due to the SATA-300 interface, but unless you are transfering huge media files, you won´t notice the difference between the two.
I highly recommend every to upgrade to an SSD
I ran an X-Bench Comparison if anyone is interested. The old MBP 3.1 2.4 Ghz Santa Rosa is first, and the new MBP 5.5. 2.53 Ghz second.
