This is my setup for a Linux laptop for video editing.

I hope kdenlive use will be fast. Disk is small and fits just one or two projects at a time, but it is really fast. I will use a separate USB box with a 2.5 inch SATA disk as additional storage. Will see how this turns out. With the SSD disk boot time went from over a minute to 20 seconds. Screen is not enough for full HD but close enough for my editing needs which target web formats anyway.
