Ok, the SSD is installed and I moved all files. Finally some more space without cleaning up the drive every 5 minutes.
After that I had problems with blender crashing for no reason as soon as i started to play back some animation frames. But it seems like i got it fixed now.
I started the Ashe & B.O.B animation and played around with some initial penetration scene. So far I'm liking how its looks and I decided to give you a visual update about how things are going atm. Gonna do a break now and continue working on it later today.
