I was already fearing that the change would only benefit low-level
benchmarks. It certainly helps writing small chunks to the buffer
that is meant for FAT32 directories, but at some point, the card
will have to write back the entire logical erase block, so you
might not be able to gain much in real-world workloads.

Of course, I also have only a very limited understanding of the
algorithm used in the Toshiba chip.
