Absolutely. You might consider moving the photo's there too. Someday you may run out of room on that desktop and putting everything on one dedicated large drive makes cloning that to other's (for backing up) a whole lot easier.
I use a server to store all my photos and presently have 4TB of storage so I don't worry to much about space.
I want to be able to work on my photo over the lunch hour or at coffee shops and not always at the desk. I have a 500GB portable drive I can use to storage the catalaog on but don't want to carry around the photos all the time.
If I can transfer the project catalog to the drive and use the smart preview to get some of my work done remotely that will help alot.
HI, that's cool you use a server to store your lightroom photos. What drive do you use for that? So when your on the go you connect to your server and all your photos will be available in lightroom? I know there are smart previews but I would like to be able to work in lightroom from wherever I am. Any suggestions?
