Synology DiskStation DS716+ NAS Testing: 

There are two aspects concerning the operation of the Synology DS716+ we need to examine next and that concerns the cooling performance and power consumption of the system.


The Synology DS716+ is cooled by a single 92mm x 92mm fan that is designed to run in two modes - quiet and cool. For the tests, I kept the fans on quiet mode as a normal user would and set up the Intel NAS Performance Toolkit to run while the volume was in RAID 1. When the tests were nearing completion, I checked the temperatures of the hard disks under the Storage Manager via the S.M.A.R.T. settings. Each one is shown in the graph below along with the ambient temperature of the testing room.

As you can see from the temps, the cooling of the dual fans are very efficient and keep the Synology DS716+ at nice working temps. Also to note, the noise level of the fans is not very noticeable. During the test the NAS was sitting next to my desk and I never heard the fans like I do on my servers.


RAID Data Protection:

The Synology DiskStation DS716+ is a two drive bay system that can support up to two 8TB drives. For the RAID options, you can choose from either one or a mixture of RAID 0, 1, or Synology Hybrid RAID. To test the ability of the DS716+ to recover from a single failed drive in RAID 1, I copied over 9GB of random files to show true "usage" and I simulated a "failure" by removing a disk drive from the unit while powered on. Since the server supports hot-swapping drives, you can remove and replace drives without having to power the unit down. I then replace the "failed" disk with the removed disk formatted and measure the time it takes to fully recover from the failure. The RAID volume took 14.5 hours to rebuild, which is really good considering the drives are 8TB a piece.




Now that we have recovered the RAID and expanded it, we can move on to the conclusion.
