Performance - more
Similarly, in gigabit average read performance (Figure 9), the Pro Duo came in last at 9.0 MB/s compared to the DS207+ at 24 MB/s.

We also thought it would be useful to compare the Buffalo products to each other to see how the Duo stacked up against the rest of the product line. Again, we looked at average performance results with a gigabit LAN connection.
For large file size writes, you can see that the Pro Duo never achieved the performance of its single drive LinkStation Pro sibling (Figure 10). It turned in a slightly better performance than the LinkStation Live did at the 32MB file size, and then dropped below it for larger file sizes. Only the new entry-level LinkStation EZ had consistently lower performance.

In the large file read performance tests (Figure 11), the Pro Duo also turned in disappointing results. From the chart below, you can see that it tracked the performance of the entry-level LinkStation EZ. At the 32MB file size, it achieved 38% of the throughput of the LinkStation Live and only 28% of the LinkStation Pro.
