The FAT cluster size is 32k, so any flash block that's a factor of 32k works well. Page sizes are usually 2k with a 128k erase block, 4k with a 256k erase block, or 4k with a 512k erase block. It's also due to ECC reasons, since a larger block size allows more efficient ECC over a larger block of data. This is similar to move to 4k sectors in magnetic drives. -B -- Brandon High : bh...@freaks.com
