Synology RackStation RS411 review

We are testing the Synology Diskstation DS1511+ 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

Data throughput is excellent, very closely matched to the DS710.

Our local PC has a fast Kingston SSD as the main drive and we are using it to ensure no bottlenecks occur on this side of the testing. Our PC is hooked up to the network and we transfer a 10GB MKV file from the PC to the NAS systems. All NAS systems are using dual drive mechanical Raid 0 configurations.

When writing, we recorded an average rate of around 53 MB/s. CPU usage spiked between 50 percent and 80 percent. and memory usage was steady at 20 percent.

With jumbo frames set to 9k we managed around 107 MB/s average which is a fantasic result. With the settings at default this dropped to around 96 MB/s. CPU usage lowered to around 50 percent and the memory demand was still around 20 percent.

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.

Impressive read performance from the RS411 unit, averaging 73 MB/s.
