NAS Reviews


To get a feel for performance of the TS-209 Pro, we ran the unit through our standard testing procedure. You can generate your own charts comparing various modes and features with other units, but I ran a few myself to give some basic numbers, and to compare the TS-209 against other comparable units we've tested.


  • The maximum raw data rate for 100Mbps Ethernet is 12,500 KBytes/sec (12.5 MBytes/sec) and 125,000 KBytes/sec (125 MBytes/sec) for gigabit
  • Drives used were two Seagate ST3250620AS 250 GB 3.5 inch SATA (vendor supplied)
  • Full test setup and methodology are described here

Figures 12 and 13 are composite read and write throughput vs. filesize plots for all of the benchmark tests we ran. These were generated using the NAS Chart Compare Benchmarks feature.

Figure 12: Composite Read Performance

Figure 12 shows that Normal and RAID 1 Read performance is virtually identical for both 100 and 1000 Mbps LAN connections, with a slight difference for gigabit LAN with 4K jumbo frames. Figure 13 shows only a slight difference for 100 and 1000 Mbps LAN connection with more of a difference with a gigabit 4K jumbo frame connection.

Figures 14-17 show the TS-209 Pro as compared to several other dual-drive NASes, the Hammer MyShare, the Synology DS-207, the Maxtor Shared Storage II, and the Iomega StorCenter. As you can see in the comparative charts, the TS-209 Pro fares well against its competitors, leading the pack in almost all cases.
