I may be missing something here, but from the set up he is discribing his raid-z should be seeing 4 1tb drives. Thus in theory he should be able to lose both 500gb drives and still recover since they are only viewed as a singe drive in the raid-z. The main draw backs being performance, and lack of ability to fully manage the 500gb drives.
