SSD for performance, partition for backup

Hey Folks

Looking to boost MacPro system performance with Lightroom and want to transfer my LR catalogues to an SSD.  I am currently running Mac OS and applications from a single SSD with my catologues on a separate WD Caviar Black HD.  Considering switching to a larger and faster SSD, then partitioning it to OS/applications on one section and Lightroom catalogues on the other.

Are there any performance gains to be achieved by running the OS/applications and LR catalogues on physically separate drives, or will a single partitioned drive suffice?

I've done exactly this with Aperture libraries. Moving them from a hard drive to an SSD definitely made Aperture perkier. As others have noted, there's no speed advantage to partitioning the SSD. There is a non-speed advantage to partitioning, though, and that is that you can easily backup your data separately from your OS and apps. Putting only OS and apps on a smaller boot volume requires less space for Time Machine and system clones. And, putting libraries or catalogs on their own volume makes it easy to have multiple backups.
