Even if you pop the uSD card out and into a Linux system, I suspect that you would find ext4 using extents would limit any gain by playing with the block size. With the default 4K block size, an ext4 extent can map up to 128MB in contiguous blocks. With 4 extents in an inode, that gives 512MB.

The other thing to remember is the Linux family of OS very often reads and writes small blocks. This was brought out years back when people were finding wildly varying results on Nooks. XDA has quite a few items on this -- SD Strange-results - or - How I learned to love CM7 on SD - Dec-11 results compiled! for one example.
