The cards were of me with the test program h2testw [...] On the "acid test" tested. Mainly because I got fake memory sticks and SD cards about two years ago, the only half had so much capacity as they have pretended. Yes our foreign suppliers (China) have also tried this. However, there was nothing like this ever in Merkanware (Kingston, SanDisk, Transcend etc.).
Because the program also displays the data rate for writing and reading (the memory are written with test files with a bestmmten memory patterns full and then read again), I could tell that this Kingston SD card a write rate of 13.7 MB / s, a read rate of 16.5 MB / s and of course is healthy. So a recommended purchase.
