FusionIO 320GB MLC random write performance

I was advised that new drivers and new firmware for FusionIO cards improve performance and stability and it is recommended to review results I’ve got about year ago.

Using the same methodology and the same box as for Intel 320 SSD, I run random writes benchmarks for FusionIO 320GB MLC card (I do not have the card I had year ago on hands).

Information about system, FusionIO drives are raw results are on Benchmarks Launchad

First graph is to show timeline for different filesizes. Benchmark starts just after formatting card and filesystem and runs around 1 hour with measuring throughput each 10 sec.

Interesting to see the same pattern as for Intel 320 SSD: the throughput starts at max, then drops down and after some peak stabilizes.

1500 sec seems enough to get stable line for all filesizes. If we take slice of data after 1500 sec and build summary space->throughput graph, it looks like:

So we still have decent declining line. The throughput drops from 500MiB/sec at peak to 110-120MiB/sec at full capacity.

And to have some fun with R/ggplot2 graphs, let’s build graph to compare FusionIO and Intel 320 SSD (with results from previous post)
