What (if anything) do I gain by mirroring partitions on the same USB drive?

I have a small amount (a few dozen items of a few kilobytes each) of essential data to store, which I will need to access over the coming decades. While the data is highly confidential, its value to others is debatable, and my budget is small.

I recently purchased a bunch of brand-name 8 GB USB flash drives to store this data. I'm wondering: does creating two partitions on each drive and storing the same data on each actually get me anything? I'm thinking it might buy me some redundancy if some of the flash becomes corrupt, but wouldn't save me from a controller or other hardware failure. I'm looking for definitive answers that can show why this is or isn't a good idea.

For clarity, I'm not talking about hardware or software RAID1, but simply creating two partitions and putting the same files on each. I have other methods for ensuring confidentiality and integrity, and I plan rotating the physical media every few years.
