We would like to thank Synology for supplying the review sample.
NAS servers that address business environments are usually multi-bay models with the ability to take many drives for more storage space, but Synology claims the DS215+'s purpose to be to successfully handle the data-protection and file-sharing needs of small- and medium-sized businesses. A closer looks at this product's characteristics shows that it has some features that make it a suitable solution for such demanding situations. The most interesting of these is the link aggregation support through its Ethernet ports. The dual-core CPU also promises high performance along with low power consumption.
The DS215+ is the smallest member in Synology's product line for small- and medium-sized business environments, and it doesn't share the same hardware with the DS415+ we had the chance to evaluate a while ago. We should also mention that the DS215+ can be connected to a Synology DX513/DX213 expansion unit through its eSATA port; however, there is a catch: connect an expansion unit to the DS215+ and it won't increase the size of its internal volume to, instead, allow for independent volumes with the additional storage space inside the expansion unit. This doesn't pose a serious drawback, but we had to point it out for those particular situations where there is the need for a single volume only.
