So how well will the Synology DS412+ perform? Lets find out through some network performance testing. This performance testing involves copying large files to and fro the DS412+ via CIFS (Windows File Service).
The equipments involved
Both the iMac 27″ and Synology DS412+ are hooked up to the LAN ports of ASUS RT-AC66U. All of these equipments are running on 1 Gigabit connection with no Jumbo Frames (default MTU 1500). Port trunking (or LACP) is not used. Do note that the theoretical limit of 1 Gigabit connection is 1000 megabits (1000 Mb/s) or 125 megabytes (125 MB/s).
A free tool call NAS Performance Tester will be used to test the read and write performance of the Synology DS412+.
The results of DS412+ speed tests
I have performed two tests:
- 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.
Taking into account that the max theoretical speed for a 1 Gigabit connection is 125 MB/s. The speed test results are not too far off from this. Perhaps the CIFS operation have too much overhead or the equipments used (iMac and ASUS RT-AC66U) are the bottlenecks. It appears that I will not be able to find out with the current set up.
Nonetheless, the speed test results are excellent. According to data specifications, the Synology DS412+ can achieve up to 205.68MBps and 182.66MBps with port trunking (LACP). Let me try to do some speed test with the Synology DS412+ as a iSCSI target.
