Typically, with modern day software, a record size of 64kb is used with larger files. With the sheer amount of data conveyed throughout the last few tests, it was hard to accurately gauge the QNAP TS-809 Pro Turbo NAS performance, and even harder to do so across different RAID configurations. In the next section, we will be comparing the data compiled through the tests we ran earlier to gauge performance over the various RAID configurations.

The results are fairly consistent between all 4 storage schemes until we reach record sizes of 1+ MB. Only at that point do we see JBOD drop off to 30MB/s while RAID 0, 5 and 6 float at the 50MB/s mark.

The Writer results fit in a small bandwidth with RAID 0 being the most consistent and JBOD showing the largest drop with increasing record size. With no surprise, RAID 0 is the fastest with Re-Writer followed by RAID 5, RAID 6 and JBOD taking up last place. I’m not surprised at this because as redundancy increases your total throughput rates decreases. The exception becomes JBOD and it is last because everything is written on one disk at a time and no overhead can be shared between the various drives.

I think this one chart really summarizes everything nicely. We can really see how the performance levels are incredibly close together between the different storage schemes. For the most part you can expect RAID 0 to have a slight edge over the rest but this only concludes the results from IOzone. We still have a few more programs to run through so let’s not delay.
