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-439 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.

It’s really no surprise that RAID 0 claims first place followed by RAID 5, 6 and then JBOD. The more disks being stripped, the first the overall performance will be. The spread between first and last space is about 10MB/s which is a small compromise for anyone looking for data redundancy.

Almost an identical story, RAID 0 and RAID 5 are mere MB/s apart with RAID 6 taking third and JBOD rounding out the last.

I was actually a bit surprised that JBOD and RAID 0 had identical results. You don’t exactly buy a 4 drive NAS just to run a bunch of disks; however, if you do then you will be pleased to hear you’re not sacrificing too much write performance.

The throughput is very impressive with the small record size but as we come back to earth, we find that the Re-Writer results don’t differ too much than the actual Writer results. They are still faster but the margin actually gets smaller and the results converge together. At first, the gap between JBOD/RAID 0 and RAID 5/6 was 40MB/s but that slowly closes to 10MB/s or less.
