Storage Spaces vs. Drive Extender

People who want to get back Drive Extender instead of Storage Spaces usually test Storage Spaces using a parity layout. Then they complain that there is no rebalancing, speed is low, and all in the same spirit. However, with all of this testing they forget that Drive Extender operates on the file level and therefore the parity is out of question. Test Storage Spaces on the mirror or simple layouts and you will get better results than in case of Drive Extender.
