I was over at the Xbit Laboratories web site checking for new information about ssd's. I found a very interesting article published last November containing facts and forecasts about Flash and Solid State Drives. There is some good news and some bad news. http://www.xbitlabs.com/articles/s
You mentioned photos and videos. Do you use Adobe products such as Photoshop? If you do, then here is a link to an Adobe web page that contains their advice about solid state drives:http://kb2.adobe.com/cps/404/kb404439.html
Scroll down to the bottom of the list to get to the link to the ssd section.
