As noted above, the TVS-463 runs QNAP's QTS 4.1 NAS OS (4.1.3 Build 20150408 to be specific) and supports all its features, including SSD Cache acceleration, Virtualization Station and QvPC NAS-as-PC features. We covered Virtualization Station in this piece a few months back.

Performance tests were run using our Revision 5 NAS test process on four-drive RAID 0, 5 and 10 volumes with a 1 Gbps LAN connection. The firmware installed was 4.1.3 Build 20150408.
The TVS-463's Benchmark Summary below shows pretty much all large sequential file copy benchmarks bumping up against the limits of the Gigabit Ethernet connection. The only exception was Windows File Copy read, which produced a relatively low 95 MB/s.
RAID 5 Ranking
Comparing NAS Ranker performance summaries shows not a lot of difference between the two products. It's mainly the combination of lower sub-ranks in Video, Backup and iSCSI benchmarks that drove the QNAP's score down. Of particular note is the TVS-463's significantly lower rsync backup throughput of 36 MB/s vs. the ASUSTOR's 68 MB/s.
QNAP TVS-463 Ranker Performance Summary Comparison
#2 rank for a new NAS platform isn't too shabby. But when you consider the TVS-463 is currently $240 cheaper than the #1 ranked Intel i3 powered ASUSTOR AS7004T, that could definitely influence some purchase decisions. And if you opt for the 4 GB model, the price gap grows to almost $300! I guess we know why QNAP decided to launch the AMD-powered Golden Cloud family.
