I found a speed test of the DS412+ - network performance and overall speed over at shadowandy.net. The tests use the free NAS Performance Tester. Two tests were performed:
- the first one using a 4000MB file; and
- the second one using a 2000MB file
For both tests, a network share on DS412+ is mapped as S:.
In the 4000MB file test, the Synology DS412+ managed to achieve an average of 110.33 MB/s write and 106.48MB/s read.
While for the 2000MB file test, the Synology DS412+ managed to achieve an average of 110.71 MB/s write and 113.55 MB/s read.
These results are, of course, excellent using a single Gigabit Ethernet connection. The maximum theoretical throughput is only around 125 MB/s, so the Synology is nearing the theoretical limit.
