I would agree, that is what I have seen happen. If one stream lags behind it just skips putting it on the drive until it is ready.

I think the 3 streams a 15MB/s continue to truck along and the 10MB/s stream writes at 10MB/s but its more stretched out, example: 15MB/s stream: # # # # # # # # # # # # # # # # 10MB/s stream: # # # # # # # # # Justin. _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
