Regarding Raid1 example code, in the CyFxMscApplnDmaCb () function, is the "CyU3PDmaBuffer_t dmaBuf = input->buffer_p" used to hold the read/write operation when data is transfered between to/from sdCard via dma?
any helpful answer is appriciated

Yes, dmaBuf in Dma callback function holds data when there is a read/write operation.
You cannot modify the data when the dma channel is AUTO. You can modify in Manual channel.
