I usually test it with something like:

file -s /dev/wd0b -> "data" (or whatever)
file -s /dev/wd1b -> "data"
cat /bin/ls > /dev/raid0b
file -s /dev/wd0b -> "executable blabla"
file -s /dev/wd1b -> "executable blabla"

If that works and wd0b/wd1b are smaller or equal in size than raid0b,
you're set.
