Actually, according to information in this AnandTech article, some high-end controllers use even weirder techniques... (They mention specifically real-time compression and real-time deduplication, and there's likely a lot more)

The compression and deduplication of the Sandforce controller show big benefits over the controllers that don't have them. But those benefits are lost if your data isn't compressable/redundant like if it's encrypted :(

Live CD

What about a live CD that you boot from, type "yes I want to trash my flash drive" and it automatically tries different partition schemes, runs benchmarks, and tells you which one is fast? Don't trust what the drive says, just try it a bunch of possible ways and see what works for real. (I'd pay $14.95 for the iso assuming the underlying code was Free.)
