Hi amogamax,
You may install the OS on SSD, however, it is not recommended by Dell. The primary purpose of SSD is to work in conjunction with the hard drive with the help of Intel Smart Response Technology and act as a cache drive for faster operations. Also, the SSD in question have limited capacity and might cause issues with the installation of software's after installing operating system.
Please reply if you have any further questions. I would be glad to assist you.
