To answer my own question, in case someone else experiences the same problem:
Using a 2nd /dev/sda2 'casper-rw' partition with an ext2 formatted filesystem on the USB stick, even when mounted as /cow with the 'noatime' option, won't prevent excessive write cycles to the USB stick for each file read. Reason: The Unionfs doesn't respect the 'noatime' option for the /cow branch. Hence, I'd not recommend using a 'casper-rw' partition on a USB stick for /cow persistency.
