The QNAP TS-239 Pro II

June 30, 2012

After working with several Marvel powered NAS appliances including the Iomega IX2, IX2-200, and QNAP TS-119P II I wanted to find a solution that was more robust for iSCSI performance.  SmallNetBuilder’s New To The Charts: QNAP TS-239 Pro II article convinced me that an Intel Atom based CPU was the upgrade that I needed.


Hardware Specifications:

CPU Intel® Atom™ (1.66 GHz) D410 CPU
Ethernet Intel 82574L (x2) 1 GbE
Flash 512 MB
SATA Intel 82804GBM/GHM (ICH7 Family)

You can see more details about it here QNAP TS-259Pro+ vs TS-239Pro II+  vs TS-219P II  vs TS-219P+  vs TS-212 vs TS-210 and here TS-239 Pro II.

Reported Write and Read Performance Numbers in MB/s:

Resource Test Write Read
SmallNetBuilder iSCSI 71.4 67
NASPT 75.8 87.8
Copy 2 GB File 57.9 57.5

I am using a single Seagate Barracuda 7200 RPM ST3000DM001 disk drive with the latest firmware.  I have also upgraded the memory to 2 GB by replacing the existing Transcend 1G DDR2 667 CL5 SO-DIMM (519259-2339) with a Kingston module KVR667D2S5/2G.

Note: It is very important to update the firmware on this drive to CC4H.  See Adaptec and the Seagate’s Knowledgebase Barracuda (1TB/disk platform) Firmware Upgrade posts regarding issues with older firmware.
