That sounds like a great idea! Is there an easy way to transfer photos from one catalog to another? I would like to upload to the ssd, delete and edit, then transfer them over to a portable drive.
You'd either have to reinstall your OS or clone the drive to move everything to the SSD. Not sure about how to do it with a mac. 120GB SSD is about $190 here
. Note that those are the slightly older 3G models, the faster 6G ones are $60 more here
. I use that brand.
I don't know much about lightroom, or catalogs. The way i'd do it is export the metadata to XMP files (control-S I think), then copy the images and their settings to the external drive. Point LR at the folder and it'll pick up your changes.
A Mac/LR person might be able to help more with details. With mac I can only help at a conceptual and hardware level, not software.
