> Why are there saying all the same block size..?

Because they are all the same block size.  It looks like that flash has
pages and blocks.  Reading/writing is a page at a time, 256 B, whilst
erasing is a block at a time, 16 KiB, and erases all the pages in the
block.  Only an erased page can be written.  Erasing tends to be slow.
See http://www.linux-mtd.infradead.org/doc/nand.html, especially the
`NAND technical view'.
