On these disk reviews, why is it that the line graphs for the iometer sustained sequential write, gigabytes written don't use properly spaced values along the X-axis? By this I mean the intervals are labeled "0, 0.5, 1, 2, 5,10, 15 (minutes)" yet spaced in such a way to indicate that the amount of time between 1 and 2 minutes and the amount of time between 2 and 5 minutes is the same (which it isn't). Last time I did math the median value of the numbers 0 through 15 wasn't 2, nor does the median value of 0-2 minutes work out to 45 second.
When graphed with equally spaced X values (based on the values at 1, 2, 5, 10 and 15 minutes as provided on the bar graph for this test), most of the drives write at a linear rate within 2 minutes of starting the test (because the SLC cache has run out by then). However, when I look at the 15 minute graph, it looks like the drives start the test slowly, then around the halfway point they all (metaphorically) rail a line of blow and the amount of data written skyrockets (not how drives out of SLC cache work). The graph for 2 minutes isn't all that much better.
I've added the links to the 2 problematic graph images here for convenience:
Graph Linky and
another Graph Linky.
