That is what I'm saying -- and is what I'm going to do in a couple of weeks.

From all what I've read about software and hardware lately:
You buy an SSD. The SSD comes with a setup software to clone your boot partition onto the SSD. You replace your current boot disk with the SSD (like: in my laptop there is only one slot for a hard drive -- but this also applies to machines with more room.)

... and to be safe, remove the old disk from the computer after installing the SSD.

I will report after I have done it, but I will wait a couple of weeks until the majority of "Kinderkrankheiten" (growing pains?) are cured.
