Performance

The 200rl was tested using our standard iozone procedure with tests run in JBOD and RAID 5 modes with 100 and 1000 Mbps LAN connections. Tests were not run with jumbo frames enabled because our standard test uses 4K jumbo frames and the 200rl supports only 9K.

Figure 8: RAID 5 Average Write ranking - 1000 Mbps LAN

Figure 8 shows the RAID 5 average Write rankings with a 1000 Mbps LAN connection and filesizes from 32 MB to 1 GB, where the 200rl tops the chart. (Open the full version of the chart to see the entire ranking.) The read chart is here and shows the same top-of-chart performance.

Note, in particular that that the average RAID 5 write performance is almost 4X that of Linksys' NSS4000 [reviewed] and Netgear's (Infrant) 1100 [reviewed] rackmount NASes. The details behind this are shown in Figures 9 and 10.

Figure 9: RAID 5 Write comparison, rackmounts - 1000 Mbps LAN

Figure 9 shows that the 200rl and Thecus 1U4500 are clearly in a similar performance class and the 200rl's slightly better average write ranking due mostly due to better performance at the 32 MB file size.

Figure 10 shows a closer grouping of read performance with some upticks in the Thecus and Infrant curves at the 256 MB file size.

You can use explore how the 200rl stacks up against other NASes or just explore other modes and LAN speeds by creating your own comparative charts using the NAS Performance Charts.
