That really depends on whether you want to test read or write 
performance. If you mean that you want to test for correct operation 
rather than performance then you need a write test to fully exercise the 
disk. Some errors will only be found on write, and conversely some read 
errors will be corrected (remapped) on write.

Create the encrypted volume first, then write zeros to it. :)
