So I grab my Samsung Galaxy Note 2, download the app "A1 SD Bench" and famous:
SanDisk 8GB Class 4 (Alt):
Read: 6,58MB / s
Write: 3,94MB / s
Qumox 64GB Class 10 (new):
Read: 14,16MB / s
Write: 8,54MB / s
So what you want more?
And yet as a warning: I have previously purchased a NoName card in major auction house. Although for 10 less, but correspondingly slow it was.
