To see how well the Pro performed, I made a few Iozone runs using 100 Mbps and 1,000 Mbps connections. The 1,000 Mbps tests were run once with 4 K jumbo frames enabled, and one with jumbo frames disabled. (For the complete story on how we test NAS products and on the new test result format, go here.)

Figures 9 through 12 show the results, along with those from a selection of comparable products including Buffalo's Gigabit LinkStation. The results don't require much explanation since the Pro clearly outperforms all the products included for comparison in all modes and speeds.

You can also see some of the Pro's results against a wider range of NASes over on our NAS Charts. It is at the top of the gigabit performance charts and is bested only by the Iomega StorCenter Pro NAS 200d with a 100 Mbps network connection.
