You should be able to look at the library function and confirm his claims. One byte writes to any flash device would be really slow as the block size on a flash device is at least 512 bytes most of the time one, larger like 2048 or 4096. So the device will be doing a read, modify write until the whole block gets replaced. Writing the whole block in one pass, will greatly speed up the process.
