Sorry to hear about your bad experiences with laptops and SSD storage.
I must have been lucky, so far.
I've been laptop based for over five years now. I did, however, start off with a double SSD system. Since then I have upgraded the SSD devices twice. Once as a new install and one as a clone.
There is no way I would bother going back to a desktop system. I love the portability of my "studio" and I can work on my creations in the most wonderful and inspiring locations. Plus I never have to worry about power interruptions.
All that said, I set my budget high and, in my opinion, bought quality gear almost from the start. I would now never bother with anything other than the Samsung Pro SSD drives as, up to now, I have never had a problem with them.
Cheers
