How old was your failed micro SD card? According to Samsung all micro SD cards should be replaced after 3 years as they claim that is the usable life span. I use and have used ScanDisk, Samsung, and Lexar micro SD cards and all have worked perfectly for at least 3 years. The only 2 that have failed were well over 3 years old.
I am currently using a Lexar 128GB microSD card in my Note 4 due to the fact that is several orders of magnitude faster than the Samsung 128GB cards. A real plus with video taking.
Your mileage may vary.
