This is correct. You might only get 100,000 to 250,000 erase cycles on
each block (2048 bytes?) and any update withing that block requires an
erase and rewrite.
I don't think you should be using Ext2/3 on Flash, you should be using
a Flash File System, because these file systems do wear leveling so
that erases are spread evenly across all the blocks.
