Hello

Data is rewritten in sector units after erasing. Therefore, the smaller the sector size, the more efficiently it can be rewritten to pinpoint.
However, if you simply compare the difference in sector size between 4KB and 64KB, The smaller the sector size, the greater the number of erases. As a result, the rewriting time will increase.
