the increase in performance to a Class 10 Aldi product is abundantly clear.
It starts copying files to the SD card.
The higher price has been more than worth it in my eyes.
The SanDisk Extreme product is more than noticeably faster standard Medion product.
Smart phones internal memory with 4 GB micro SD memory cards need mandatory extensions;
on the one hand to store multimedia data, on the other hand to store apps on microSD card (if possible).
Especially with Apps on SD performance increases with this "SanDisk Extreme"
because the apps are started and operated from the SD card.
Slow sd card, slow app - good example apps with large databases:
Navigation / maps, Offline Translator.
Whether a SanDisk brings extremely plus or extreme pro another performance enhancement;
one would have to try it, or any remains left to itself.
I think this is also dependent on the performance of the memory controller of the smart phones;
probably are the only considerations in the parts per thousand range.
I'll stay with at least this category "Extreme", even in tablets and digital cameras.
