The TS-869 Pro was tested with 3.8.2 Build 20130301 firmware using our standard NAS test process.
The Benchmark Summary below shows pretty consistent Windows File Copy performance for RAID 0, 5 and 10 modes. RAID 0 write shows the highest results at 107 MB/s, with 97 and 100 MB/s for RAID 5 and 10, respectively.
File Copy read has even less variance at 106, 104 and 104 MB/s for RAID 0, 5 and 10, respectively.
QNAP TS-869 Pro Benchmark Summary
NASPT File copy results are higher than their Windows File Copy counterparts for write (134, 127, 128 MB/s) , but lower for read (92, 93, 93 MB/s) for RAID 0, 5 and 10 respectively.
iSCSI target write performance to target created on a RAID 5 volume came in at a respectable 87 MB/s, with read slightly lower at 82 MB/s.
Best attached backup performance of 112 MB/s was obtained with eSATA / NTFS, USB3 /NTFS and USB3 / FAT.
For a competitive look, I ran filtered RAID 5 File Copy charts selecting four other Intel Atom D2700-based NASes for comparison, i.e. the ASUSTOR AS-604T, Synology DS412+, Thecus N7510 and the very recently reviewed LaCie 5big NAS Pro. All RAID 5 and 10 tests are run using four-drive volumes, to not give an advantage (or disadvantage) to a NAS with more drives.
Like we've been seeing quite a bit with Atom-based NASes, the competitors change positions from benchmark to benchmark, but results are close enough that it would be difficult to detect a significant performance difference among the group in real-world use. The possible exception in this group is the LaCie 5big NAS Pro, which lags significantly behind the pack in three out of four benchmarks compared.
RAID 5 File Copy Performance comparison
Just like the TS-569 Pro and other QNAP offerings, QNAP delivers a high quality NAS, packed with performance and features. And like other QNAP products, it is relatively expensive.
As mentioned in the TS-569 Pro review, we have seen very little performance difference among the D510, D525, and D2700 Atom variants. So value-conscious buyers might want to look for a deal on less-expensive models based on Intel dual-core D5xx Atoms.Whatever you decide, you'll be getting a eight-bay NAS that is one of the best out there. Just not one of the most budget-friendly ones.
