We are testing the Synology DS411j within our gigabit network which is pretty much as good as you will get for a home or small office environment. It is a mixed network with several 1GBit switches for ultimate performance.
Reference Test PC:
Processor: Intel Core i7 920 @ 4ghz
Storage: Kingston 128GB SSD V+ Series
Motherboard: Asus Rampage II Gene
Graphics: Geforce GTX285 2GB
Memory: Corsair Dominator 1600mhz @2000mhz
Network: 2x Belkin 16 Port Gigabit Switches
Operating System: Windows 7 64 Bit Ultimate
Firstly we perform a native network test to ascertain pure data throughput. Jumbo Frames have been set to 9k.
Pure data throughput is impressive considering the budget market, we wouldn't expect this unit to be in the same region as the higher models such as the DS710.
We averaged 18 megabytes per second when writing to the DS411j, its certainly no record breaker, but it holds steady at these speeds.
Memory use hovers at around 35 percent when writing to the Raid 0 configuration, consuming around 45 mb of ram. Processor time is between 30% and 40% with this load.
We averaged around 36 mb/s which is a great result and easily capable of streaming 1080p content across a network.
Network flow virtually doubles, which also drives up CPU time from under 40% to around 60-65% utilisation. Memory demands stay the same as with the write test. We like the way Diskmanager colour codes read and write graphs with green and red respectively.
Next we created a folder of files, 500mb/s in size with a variety of data , from small database documents to larger jpgs and bmps. We expect to pay a slight penalty as we are using Jumbo frames set to 9k, however performance should still be good.
Mixed file transfer rates take a slight hit as expected although performance is still quite good, averaging around 28 mb/s when reading from the drives.
