Performance - 100 Mbps LAN

D-Link DNS-323: A brand-name NAS worth waiting for.
By

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.

NOTES:

Firmware version tested was 1.01 Drives used were two mode, i.e. independent drives. Both products exhibit 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.

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.
