Synology DS414j: An Ideal Backup NAS

Multi-Client Performance - CIFS

We put the Synology DS414j through some IOMeter tests with a CIFS share being accessed from up to 25 VMs simultaneously. The following four graphs show the total available bandwidth and the average response time while being subject to different types of workloads through IOMeter. IOMeter also reports various other metrics of interest such as maximum response time, read and write IOPS, separate read and write bandwidth figures etc. Some of the interesting aspects from our IOMeter benchmarking run can be found here.

All the units compared with the DS414j in the above graphs come with two GbE links except for the Asustor AS-304T (which only has one). Compared to other units, we find that the Synology DS414j exhibits better consistency in performance as the number of simultaneous connections goes up.
