The Tests Many readers found our 3D iozone plots confusing (see Figure 1) and uninformative, since caching effects from the computer doing the reading and writing tended to dominate the plot. So after some experimentation and consultation with iozone's creator,...

Many readers find our 3D iozone plots confusing and uninformative, since caching effects from the computer doing the reading and writing tend to dominate the plot. After some experimentation and consultation with iozone's creator, Don Capps, we've decided to...

that, thanks to IOzone's current maintainer Don Capps, I'm somewhat savvier than I was for my ioGEAR BOSS vs. Tritton ASAP review about how to use IOzone properly! Figure 4 shows a 3D surface plot of the Office's NDAS (Ethernet-connected) write performance...

better comes along. The full testing setup and methodology are described on this page, so I'll just concentrate on the results here. IOzone runs a series of read and write tests using different record and file sizes. But to keep the comparison plots simple,...
