- Firmware version tested was fs-bc-1.3-b524
- The full testing setup and methodology are described on this page
- To ensure connection at the intended speeds, the iozone test machine and NAS under test were manually moved between a NETGEAR GS108 10/100/1000Mbps switch for gigabit-speed testing and a 10/100 switch for 100 Mbps testing.
While you can create your own charts and select which products to compare, we chose to include read and write performance charts for RAID 5 using small file sizes with a 1000 Mbps connection and both standard and 4k jumbo frame sizes.
We used the chart small filesize mode instead of the usual large filesize mode because many readers have expressed interest in seeing performance for small file transfers. Note that small file size performance is highly influenced by OS cache effects
For comparison, we included a few comparable desktop RAID 5 NASes: the Freedom9 freeStor 4020 (a veritable clone of the EDR), and Infrant NV+. The 100 Mbps Ethernet reference line is also included to provide a consistent point of reference. 100 Mbps was used instead of 1000 Mbps because the 1000 Mbps line would have compressed the data too much.
The EDR had an average throughput for small file size writes of 9.5 MB/s for 1000 Mbps RAID 5 and 17.3 MB/s for 1000 Mbps 4k jumbo frame RAID 5. Average small file size read speeds were better at 18.8 and 22.4 MB/s for 1000 Mbps RAID 5 and 1000 Mbps 4k jumbo frame RAID 5 respectively. Details behind these averages are shown in the throughput vs. file size plots in Figures 13 - 16.
Figure 13: Write performance
You can see that the Freedom9 freeStor results track the EDR's pretty well in Figure 13. Figure 14 shows that both products take better advantage of 4k jumbo frames than the Infrant NV+.

Figure 15: Read performance
On read tests, the NV+ again doesn't get much of a boost from jumbo frames. But it still stays ahead of both the EDR and freeStor.
Figure 16: Jumbo frame read performance
While the EDR does pretty well with small filesizes, it ranks near the bottom of tested NASes for large file size writes with an average throughput of 5.6 MB/s for 1000 Mbps RAID 5 and 7.9 MB/s for 1000 Mbps 4k jumbo frame RAID 5.
