Successful product - But 30 MB / s!

I think about the quality and durability of SanDisk products I need to lose any more big words. The company is not in vain leader with its products and without exception every SanDisk Memory Card that is in my own - and these are some :) - still works without problems.

A note to the rate of new SanDisk Mobile Ultra SanDisk are on the packaging "30MB / s" on - Matters involving this value I can not understand. I have the card's performance with various USB 3.0 card readers and measured it come to an average of 46.0 MB / s (read) respectively 9.6 MB / s (write). For a card that has been developed for mobile use is ideal, because the write speed is sufficient for virtually all mobile devices and on your home PC, data can be transferred very quickly to the hard drive. Meaning making "30MB / s" still not ;-)
