The random write results paint somewhat of a different picture compared to the previous test – and it was bad news for Synology’s latest NAS. Here the DS410j appeared to lack any real horsepower with a throughput of just 24MB/s for both the read and write tests. Performance was again similar to that of the DS109, while write speeds were 42% greater when using the Promise SmartStor NS4600. Finally, we used the SiSoftware Sandra 2009 benchmark to measure network performance. With a throughput of 64MB/s, the Synology DS410j did rather well here, and was the only tested NAS device capable of matching our test system.
