On my Spreadtrum platform, I did not see any obvious performance changes in 4K block size when changing to use hsq for the SD cards, I think the reason is the SD card works at a low speed on my platform, and most of time is spent in the hardware. But we can see some obvious improvements when enabling the packed request based on hsq, that's why we still add hsq support for the SD cards.
