Single Client Throughput

HD Video Play - 720p HD stream from Windows Media Player, 256kB reads

HD Video Record - 720p HD stream, 256kB writes

File Copy from NAS - 4GB file copy, 64kB reads

File Copy to NAS - 64kB writes

For testing, we used four 960GB IronWolf 110 SSDs. This allows us to reach the full potential of the hardware, especially in mixed workloads. We ran each scenario three times and tested each with 1Gbe and 2.5Gbe.

Starting off with RAID 0, we immediately see the benefits of 2.5Gbe in our single client testing. Playback goes from 112.7 to 279 MB/s while File Copy operations to the NAS reach 225 MB/s and 278 MB/s from the NAS.

Looking at RAID 5 we see a boost in both Video Record and File Copy to the NAS reaching 197 and 192 MB/s respectively. Playback gains a marginal 10 MB/s while Office Productivity is tripled.

In the last of our single client testing, we look at RAID 6 which sees great gains in Record and Copy once again. Directory Copy to and from seems to gain a good bit here as well.

Benchmarks – Sequential and Workloads

Our Sequential read/write workload is centered on 128K transfer sizes at QD32.

Looking at sequential performance over iSCSI it's quite clear, and we knew this coming in, 2.5Gbe is far superior. In RAID 0,5 and 6 we see throughput go from 112,118 and 97 MB/s to 278,202 and 283 MB/s.

Sequential Write sees the same level of increase going from ~113 MB/s to ~220 MB/s.

Moving into workloads, you will notice a smaller jump in performance due to us reaching the limitations of the hardware itself. Starting with RAID 0, we see about 500 IOPS between 1Gbe and 2.5Gbe across the board.

Getting into RAID 5, we start to see more of a gap between 1 and 2.5Gbe. Web Server gets a 1000 IOP boost moving to 2.5Gbe along with Workstation.

RAID 6 shows a good amount of gains as well, Database getting a good 750 IOP boost next to Email Server which sees 1000 IOPs increase.

ABOUT THE AUTHOR - Tyler Bernath

Growing up in a small farm town in northern Ohio, technology was never around unless it was in a tractor. At the early age of nine years old, my parents brought home our very first PC and I was instantly hooked and quickly learned what it meant to format a hard drive, spending many nights reinstalling Windows 95 as my parents slept. As I grew up, many things changed around me, but my love and enthusiast nature always kept my PC at my side. Eager to get deeper into technology, I started reviewing products.
