I have a new SDHC Extreme HD Vdeo C10,
Iǘe tested it With CrystalMark 3.0 throug an USB2.0 adapter and it gives me the disapointing transfer rates of 19.8 Mb/s reading, and 6 Mb/s writing.
I understand that USB 2.0 supports a maximum of 480mbps that would be 60MB/s.
So, Is this related to UHS-I protocol?
How do I get the “about” 30Mb/s promised by the 200x rating, or even the 10Mb/s sustained writing of the Class 10 ??
