NAS HDD Showdown: WD Red vs. Seagate NAS - Test System Setup

NAS HDD Showdown: WD Red vs. Seagate NAS

We've wanted to put these two drives together for a showdown ever since Seagate announced its NAS hard drive that competes with WD's Red NAS drive.

Our NAS test 'system' has migrated to a full 45u rack like what you'd find in a datacenter. There are ten servers that attack the target NAS with 120 Hyper-V installations of Windows 7 64-bit, each with a dedicated gigabit Ethernet port. The systems feed to three Extreme Networks Summit 400-48 switches that link together via Extreme Network's proprietary link cable system. One switch has a two 10GbE Xenpak adapters installed. When testing NAS products with 10GbE capability, the NAS connects to the switch via single or dual 10GbE courtesy of an Intel X520-SR2 installed in the NAS.

 

This level of testing wouldn't be possible without the help and support from several companies, many of which have little to do with NAS products. We would like to thank AVADirect, Antec, Corsair, GIGABYTE, Icy Dock, Kingston, LSI, Noctua, Rosewill and Western Digital for their much-appreciated support.

 

Intel NASPT

 

The Intel NAS Performance Toolkit (NASPT) is a file system exerciser and analysis tool designed to enable direct measurement of home network attached storage (NAS) performance. Designed to emulate the behavior of an actual application, NASPT uses a set of real-world workload traces gathered from typical digital home applications. Traces of high definition video playback and recording, office productivity applications, video rendering/content creation and more provide a broad range of different application behaviors.

 

TweakTown Custom 120-Client Office Test

 

The TweakTown Custom 120-client Office Test uses 120 Windows 7 Hyper-V installations and custom software to stress each NAS with traces from Microsoft Office tasks. Both throughput (in Mbits per second) and latency (in milliseconds) are measured.

 

Thecus Top Tower N6850

For this test, we're using a Thecus Top Tower N6850 with an Intel X520-SR2 10GbE Ethernet card. This combination allows us to test at speeds higher than 1000 MB/s in our multi-client test. The single user test system is limited to gigabit Ethernet, the same limitations found in most homes and offices.
