Would you partition it if the only data that will be on it is the photos and videos that I edit. Once done with the files I will move them off the SSD.
Yes, because your backup image could be taken while you have data files on the SSD.
For example, the SSD with my operating system and programs is around 50GB, but it compresses down to a 20 - 25GB image file. If I put a wedding or family event on there and took an image that could easily double or triple the size of your image.
If you don't plan on taking disk images of your operating system disk you can do whatever you like. Reinstalling an operating system and programs takes maybe a day, so if you can tolerate a day of downtime you might not bother. I do, because getting the OS, Office, Adobe stuff, web browsers, etc, etc installed and configured is a pain in the butt.
You probably don't need a 500GB SSD. The main benefit of an SSD is storing cache and catalog, as it provides rapid access to those many small files. Hard drives are plenty fast enough for storage of RAW files. Putting your RAW files into the place they'll eventually live makes for an easier, more consistent backup system. Prices are pretty low now though, so no real harm getting a bigger one. I actually have two smaller SSDs rather than one large partitioned SSD.
If you have enough RAM the RAW files tend to be cached there anyway. Once I cull a wedding I end up with around 10GB of RAW files, which easily fit into my 16GB of RAM even with the OS and other software running.
