The DNS-323 really shines in the HD playback tests, turning in its highest performance numbers across all the tests. The playback tests are more dependent on raw data rate capability and managed to push data through at drive configurations ranging from around 19-22 MB/s in the single file test. We also see the biggest gains in throughput from both RAID 0 and enabling jumbo frames here. If streaming multimedia were to be the main use, the DNS-323 would be more than capable of achieving acceptable data rates.
