Performance - 100 Mbps LAN
As with all our NAS testing, IOzone was used to check out the file system performance on the 323 (the full testing setup and methodology are described on this page). Tests were run in "Standard", JBOD and RAID 1 modes with 100 and 1000 Mbps LAN connections. To ensure connection at the intended speeds, the iozone test machine and the 323 were manually moved between a NETGEAR GS108 10/100/1000Mbps switch for gigabit-speed testing and a 10/100 switch for 100 Mbps testing.
- Firmware version tested was 1.01
- Drives used were two Western Digital WD800JD 80GB 7200RPM SATA hard drives with 8MB of cache supplied by D-Link
- Keep in mind that the maximum raw data rate for 100Mbps Ethernet is 12500 Kbytes/sec and 125000 Kbytes/sec for gigabit
Figures 16 and 17 show write and read performance for the 323 and HP Media Vault in "standard" mode, i.e. independent drives. Both products exibit the typical fall-off in performance with larger file sizes and while the 323 comes out on top for write, it's a tougher call for read.

Figure 17: Read performance comparison - Standard mode - 100Mbps
The JBOD mode plots shown in Figures 18 and 19 and RAID 1 plots in Figures 20 and 21 add the Thecus N2100 to the comparison and follow a similar pattern to the "standard mode"—323 comes out on top for write, but mixed results for read.
