128GB, yes. Samsung? I prefer SanDisk. Probably the same quality (they're both manufacturers, they don't buy their chips from other companies - and they're the only 2 manufacturers), but SanDisk is a pleasure to work with if you ever have a problem (which I haven't since they came out with the SD card around 2000). I once emailed them with a question late on a Sunday evening. I had an answer when I checked my email about noon eastern time (9AM their time) on Monday. Not shabby.
