Thanks Park. Can you tell me the testing steps you used?
During the test, has there any background operation been started?
I think two cases can be tested to check whether there is performance improvement or not.
One is doing background operations when card is busy for reading/writing. The other is doing background operations when card is idle.

Thanks
Chuanxiao
