Random Data Transfer by Size
We expect random reads to slow down as file size increases, since we're measuring IOPS. Thecus' N5810 Pro starts out with the highest 4KB random read IOPS, but drops below the other systems at 8KB, where it rides the low end of the group before merging back with other products at 32KB blocks.
The random write tests with increasing block sizes also shows cache affecting performance. The N5810 Pro fares well, even if it doesn't always outperform the other products.
