I have the difficult to directly write, erase and read data(not through the standard file reading/writing)on Flash memory with Bitsy Plus. What is the minimum block size I can use to erase flash memory each time? Any sample or suggestion?

One sector size is 256Kbyte (128Kbyte x 2)
As you know, to update (erase and write) flash, whole data in a sector should be erased.

Hong, you may have misunderstood one of the features of our CE builds. We include a flash disk driver. It shows up as the "\FlashFX disk" under My Computer on our CE drivers. Everything you store there will be there the next time you power-up your system.

Our flash drivers manage the flash space and include load-leveling algorithms that will maximize the life of your flash. Use the standard CE APIs for reading and writing data to files under that folder.
