I have a new macbook pro and am planning on installing 2 ssd (removing the dvd drive). If one ssd is for applications and the second is for data, what should I do for aperture and photoshop scratch? Should I just point aperture and photoshop to the data drive for scratch or should I create 2 partitions the data drive and assign the smaller one as scratch? The files I'm working on will be on the data drive so I guess in either case I won't get the benefits of a separate scratch volume?

Thanks

With SSDs, you don't really need a dedicated scratch drive. Aperture, for instance, doesn't (to my knowledge) even use a scratch drive.

Scratch drives are useful to mitigate seek times that severely limit throughput. SSDs have seek times that are pretty much two orders of magnitude faster (i. e. a factor of roughly 100!) than your typical harddrive. If you have bought expensive SSDs, also throughput will be a lot larger, very good SSDs can saturate SATA interface.

If you work with harddrives, putting a scratch volume on the same volume as the data volume is pointless, you'll just eventually run into problems with free space.
