Some of the manufacture doest not really denote their proper speed according their advertise speed why ?
Here are some following examples
A Data 8 Gig Class 10 Speed
Here is a A Data 4 Gig Class 6 Speed
and here is Kingston 4 Gig Class 4 Micro SD Speed :wub:
See that doesn't make any sense at all
Why a class 4 run faster then Class 6 speed card?
BTW
OS is Win7 Pro 64bit
Test off SD Card (Micro is off its SD card Jacket)
