We are continuing our set of articles dedicated to Synology’s DS916+ mid-range NAS units. Remember we don’t dispute the fact that Synology is capable of delivering a great set of NAS features. Instead of this, we are conducting a number of tests on a pair of DS916+ units to define if they can be utilized as a general-use primary production storage. In Part 1 we have tested the performance of DS916+ in different configurations and determined how to significantly increase the performance of a “dual” DS916+ setup by replacing the native Synology DSM HA Cluster with VSAN from StarWind Free.
