Thanks for the suggestion, but I want to use Dropbox to sync files from my desktop to the notebook. On my other notebook (mechanical HDD), I setup a TrueCrypt container and put my Dropbox folder inside of that. Would that be feasible with an SSD?
Dropbox allows you to sync your files online, that will be depend on the internet connection speed. For example if you use high speed internet like verizon FIOS, you can get fast download speed, and writting speed on the SSD compare the regular 7200rpm HD.
