Welcome to AAC!
why the erase block of nand and nor flash differ, which lead to drastic change in the erase cycle along with write speed?
A block is the smallest unit of storage that can be written or erased. This impacts write performance.

NAND and NOR FLASH are not interchangeable. The best option depends on many parameters. Will the data change frequently or be mostly read, do you need direct addressing/code execution, can you implement error detection/correction, what storage capacity is needed, ...
