I've used a ext4 formatted, unencrypted (!) 64GB SanDisk Extreme USB 3.0 
thumbdrive together with Unison. I sync a collection of documentation, 
some application configurations and a bunch of git repositories to it. 
The sync was done 4-5 days a week. The amount of changes was less than 
5MB a day.

IMO SanDisk is a trustful company with products of high quality. But the 
thumbdrive has not even lasted a year!

By the way... hdparm reports that the thumbdrive supports TRIM, but I was 
never able to use it!

So much for the topic "the firmware will do that". ;-)
