I bought this 64 GB unit for my new Samsung Galaxy S IV. I wanted the maximum size for music and the copious number of pictures i take of my kids and other things.I like the read and write speed on this card. I like the size but would have been happier with a bigger card but this is the max for my phone.Always happy with SanDisk, you will not be sorry you paid a little more.Edit: Should not have put "they have never let me down" in the title! 3 months in, I have been having problems with the SD card slot on my Galaxy S4. Not sure if it is the phone or the SD card moving in the slot. T-Mobile have sent me a new phone so we shall see.Edit 2: 4 Months in and I am having more problems with the same card. I received a new phone from T-Mobile and the same problem continues to occur. I have formatted the card twice and this gives a little time before the problem reoccurs. I have spoken to SanDisk and will call them again to have this card replaced. I will let you know how this goes.
