I would also point out that the SamSung class 10, 32Gb is the best of the 
lot in my experience.  In my work on a raspberry pi-3b, I thought I had 
better see about making an image of what I had, using around 7Gb of a 
32Gb micro-sd card, I bought the working samsung in and copied it to a 
class 10 sandisk of 32Gb. Put it in the pi's socket, much longer to boot 
the armhf version of debian jessie. less than 10 edits of the 2 config 
files for linuxcnc later, the card was dead. These files are presently 
in the  5 to 10 kilobyte range for size. Put the samsung back in and 
re-invented the wheel I was working on, then cloned it to the 2nd 
sandisk card I had bought at the same time. 3 days later that card was 
toast. Put the SamSung back in it. That was in January, and I'm still 
developing on it. No hiccups, the SamSung Just Works(TM) where $30+ 
worth of sandisk was gone almost before my coffee was cold. I think 
amanda is backing it up every night, claims it is, so when this card 
dies from overwriting, I'll just re-install jessie on a new micro-sd 
card, install amanda and recover.  But it won't be to a sandisk. Might 
be to an even bigger SamSung, because in these cards, bigger means 
longer life in write cycles.

Cheers, Gene Heskett
