Parkdale is simple utility for measuring drive write and read performance and runs on mapped networked drives. It copies data back and forth between targets so is not a synthetic benchmark. However, it is limited to fixed file sizes. I found it quick and useful for comparative testing.

Here’s a look at a local SSD RAID 0 drive array using Parkdale.

ATTO Disk Benchmark

ATTO Disk Benchmark is commonly used for hard disk benchmarking, so the question is, why are we talking about it here? The program can be fooled into thinking a remote network drive is local and therefore provides a good idea of how a RAID array accessed over 10GbE will perform.

The SUBST command can be used to create a drive mapping that ATTO will see as local. Assuming you have an m: drive not already assigned, the command below (run from the command prompt) will do the trick:

subst m: \\NAS_name\disk_share

The screengrab below shows a six disk RAID 0 array analyzed by ATTO Disk Benchmark over a 10GbE connection.

Intel NAS Performance Toolkit (NASPT)

There are many NAS tests already published (including those here on SmallNetBuilder) using Intel's NASPT. It uses real world (although dated) program traces to evaluate network storage performance. Here’s an analysis of Qnap’s TS-470 Pro over 10GbE:

One of the problems with this tool is that system RAM over 2 GB will skew some benchmark results considerably. Therefore you need to limit your system RAM to 2 GB using tools like msconfig (type in “msconfig” to run the command as illustrated below) if you want realistic results using NASPT:

Adobe PPBM5 and PPBM6

If you are interested in evaluating how well video editing and encoding might work over a 10GbE network using Adobe products, Bill Gehrke and Harm Millaard's Premiere Pro Benchmark for CS5 (PPBM5) and Premiere Pro Benchmark for CS6 (PPBM6) tools are worth checking out. I’ll cover my results testing with these tools later in this series.

You can download the older test series at or the newer (takes longer to run) version at

That's it for now. Next time, we'll look at how QNAP's TS-470 Pro does as a 10GbE-connected NAS.
