The TS-569 Pro was tested with 3.7.3 Build 20120801 firmware using our standard NAS test process.
The Benchmark summary (Figure 5) 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 98 and 100 MB/s for RAID 5 and 10, respectively. File Copy read has a little more variance, but is still consistent at 96, 93 and 100 MB/s for RAID 0, 5 and 10, respectively.

NASPT File copy results are higher than their Windows File Copy counterparts for write (133, 126, 131 MB/s) , but lower for read (88, 85, 91 MB/s) for RAID 0, 5 and 10 respectively.
iSCSI target write performance to target created on a RAID 5 volume came in at 93 MB/s, with read slightly lower at 88 MB/s.
Attached backup tests were run with our new higher performance Startech USB 3.0 eSATA to SATA Hard Drive Docking Station (SATDOCKU3SEF) containing a WD Velociraptor WD3000HLFS 300 GB drive. Best attached backup speeds were attained with eSATA and NTFS, clocking in at of 109 MB/s, worst was 26 MB/s on USB 2.0 with FAT.
Rsync backup to the NAS Testbed running DeltaCopy acting as an rsync target came in at a typically-measured 37 MB/s.
For a competitive look, I ran RAID 5 File Copy charts filtered for dual-core Atom processors. Note that RAID 5 (and 10) tests are run with four drives so as not to give an unfair advantage/disadvantage to NASes with more than four bays.
As we have seen previously, the latest-generation Dual-Core Atoms (D2700, D2550) don't seem to provide a significant performance boost over previous-generation D525 Atoms. The write comparison in Figure 4 shows the TS-569 Pro having comparable performance to the D525 1.8 GHz Atom-based QNAP TS-559 Pro II. The other similarly-performing NASes (Synology DS2411+ and Thecus N4800) use the dual-core 1.8 GHz D525 Atom and dual-core 2.13 GHz D2700 Atom, respectively.

RAID 5 File Copy Read falls just a bit, with the TS-569 Pro as much as 10% lower than some other Dual-Core Atom NASes, but still turning in respectable numbers.

As always, QNAP delivers a high quality NAS, packed with performance and features. But they also are not afraid to ask top dollar for them. Since we have seen very little performance difference between the D510, D525, and D2700 Atom variants, it would be reasonable to suggest that if you are able to find a good deal on an earlier model based on the D5xx processors, you should jump on it. At any rate, whatever your decision, you'll be getting a five-bay NAS that is one of the best out there. Just not one of the most inexpensive ones.
