Average Response Time
In short, the average response time is the average amount of time a storage device takes to receive a data request, find the corresponding data, access it and return the requested results. The result depends on various factors, including network bandwidth, the number and type of data requests, the technical characteristics of the hardware on which the data is stored, and the number of users that perform these data requests. For the results below, we assume that the NAS is accessed by a single user only. However, we intend to perform multi-user client-response tests soon, once we finish building our new NAS test system.
The following graph shows the NAS server's overall performance in all the tests we conducted using our custom-made software.
The DS215+ achieved high network transfer speeds with non-encrypted files; however, performance with encrypted files was significant slower because the Alpine SoC doesn't support the AES-NI instruction set. Since this is a business-centric NAS, Synology should use a SoC that supports the above instruction set, which would enable it to offer high speeds with all sorts of files.
Let's now compare the performance of the DS215+ to that of other NAS devices.
