Dear harm millaard
Thank you so much for your answer me, but how many Gigabyte for hard drive to Run the system very well with adobe cs4?

For OS & programs a 80 GB SSD or a 150 GB HDD will suffice. The reason for the difference is the fill rate. If you are looking for a fast extra internal disk, have a look at the Samsung Spinpoint F4. The 320 GB version goes for around € 30 and is a great choice for OS & programs.
