128GB: Hammer-capacity, but with dysgraphia

Background:
When buying a 64GB micro SD card decency, reported many reviewers about data loss when Sandisk. I then waited for Samsung, bought 2 piece (SLR + phone) and never had any problems, despite high write volume. 128GB, there was only from Sandisk. So buy Sandisk (yes has 10-year warranty), and fallen. The 2013er version with Readmax = 30MB / s, although only once tackled and put into cell phone, after 4 months of his duty from now on same.

Because even after weeks of waiting time still no (similar priced) alternative is to see, I try it again with Sandisk.

The advertised speed of 48MB / s is almost reached, but when writing (1GB test file size) is
the card certainly not the fastest.

As long as I have no loss of data, the card capacity and speed gets 4 stars ....
(Including the understandable slump when writing "Random Write 512K", which had been the previous card here costs, a point)
