My experience is that when a spinning hard drive fails, it's curtains for 
everything,. I have been led to believe that when a memory card, and I'm 
assuming that a SSD is similar, just one spot is dead, not the whole thing. So 
can we assume that a SSD failure would be less catastrophic?

I have also "heard" that the higher percentage of the SSD used, the more wear 
happens on the remaining storage. 

I have M.2 PCIe drive in my main PC. They are know to run hot. Not sure if that 
affects reliability? Are the SSDs in the laptop M.2 Sata or M.2 PCIe? For 
performance, a PCIe M.2 is pretty fast and Raid 0 for speed seems overkill. 
Raid 0 does increase the volume size. Again, IMO, if you need the main drive to 
be as large as possible, raid 0 will help, but not sure on the performance gain 
advantage.
