I believe these have been released recently.
Samsung 128GB(U3) MicroSD EVO Select $US44.99 ($Au60) plus delivery.
Samsung 64GB (U3) MicroSD EVO Select $US22.99 ($Au31) plus delivery.
The 128gb states up to 100MB/s read and 90MB/s write.
The 64gb states up to 100MB/s read and 60MB/s write.
The 128gb is as fast as the Samsung pro and cheaper than the normal evo(u1).
The 32gb is only 95Mb/s read and 20MB/s write.
I am considering getting 4 x 32G ones to use with my GoPro Hero5 for my upcoming trip. How easy or difficult is it to back up photos? Would I be better off getting a GoPro subscription and backing up to the cloud?
