QNAP TVS-x63 (TVS-463-8GB): AMD Powered NAS

Performance

Intel_01

We start off by taking a look at how the NAS performs with Intel NAS Performance Toolkit across various RAID levels. We also included the data from encryption to see how would it impact on the performance. Off the bat, we can see that the NAS performs very well when comes with HD contents reading and writing. The AMD SoC certainly is capable of delivering excellent result compare to the Intel based NAS. Even with concurrent read and write and multiple playbacks, the NAS is able to deliver excellent performance.

With hardware assisted encryption support, the NAS is able to maintain a good performance. At most there is about 10% penalty. The RAID 0 performance is almost the same with and without the encryption. Though RAID 5 performance got larger impact but still manages to deliver great result.

Similar result can be seen with the file transfer tests where the NAS continues to delivers excellent performance. Though, we can see that writing data to the NAS under RAID 5 has  roughly 20 to 30% performance loss with the encryption enabled.

Iozone

We ran IOZone across the different RAID level with and without the encryption. The results are very similar across the different RAID  levels. So we only include the result from the RAID 5 with encryption data here.

Write performance is good here but the NAS seems to take a small dip at file larger than 2GB. Still, the write performance is still great where the unit maintains close to 100 MB/s transfer rate, just a tad shy of the 125 MB/s that gigabit ethernet offers.

Iozone02

Similarly the re-write result shows the NAS delivers excellent performance reaching the 125 MB/s theoretical peak performance of the Gigabit ethernet.

Iozone04

Read and re-read performance is just as good and consistent across various file sizes. Notice that smaller transfer size hovers around 80 MB/s but larger size definitely is capable of delivery 100 MB/s.
