Synology DiskStation DS916+ Review

Speed Testing the DS916+

With both volumes ready for use. It is time to perform a speed test to check the transfer performance of the Synology DS916+.

I will be doing the speed/ performance test to Volume1 and Volume2 separately to see if there are any noticeable differences between the Seagate IronWolf NAS hard drives and Western Digital Red hard drives.

 

Test Equipments

For this speed, I have connected the following devices together:

  • Synology DS916+;
  • iMac 27-inch (mid 2011); and
  • Synology RT1900ac

The maximum theoretical speed is limited by the single Gigabit link (1000Mb/s or 125MB/s).

As for software, I will be using HELIOS LanTest and Blackmagic Disk Speed Test to simulate the workload and recording of performance metric.

 

Seagate IronWolf Speed Test

DS916+ with Seagate IronWolf averaged 104.2MB/s and 105.4MB/s for writing and reading respectively

On the Blackmagic Disk Speed Test, the DS916+ with Seagate IronWolf averaged 111.0MB/s and 110.1MB/s for reading and writing respectively

 

Western Digital Red Speed Test

DS916+ on Western Digital Red averaged 103.6MB/s and 105.3MB/s for reading and writing respectively

On the Blackmagic Disk Speed Test, the DS916+ with Western Digital Red averaged 110.9MB/s and 110.3MB/s for reading and writing respectively

 

Seagate IronWolf Encrypted File Share Speed Test

DS916+ with Seagate IronWolf for encrypted share averaged 56.3MB/s and 104.1MB/s for writing and reading respectively

On the Blackmagic Disk Speed Test, the DS916+ with Seagate IronWolf for encrypted share averaged 111.9MB/s and 65.4MB/s for reading and writing respectively

 

Western Digital Red Encrypted File Share Speed Test

DS916+ on Western Digital Red for encrypted share averaged 55.4MB/s and 101.5MB/s for reading and writing respectively

On the Blackmagic Disk Speed Test, the DS916+ with Western Digital Red for encrypted share averaged 110.9MB/s and 65.3MB/s for reading and writing respectively

Temperature of the Disks during Speed Test

The Seagate IronWolf averaged 38.5℃ while the Western Digital Red averaged 36℃

Good Performance

The Synology DS916+ performed well for the speed test. The reading and writing speeds to the file share averaged around 111MB/s and 110MB/s. It is also responsive in terms of handling multiple files as seen in the above results. The average CPU usage was around 25% for the speed test in clear.

In the encrypted file share speed test, the writing speed is noticeably impacted. The average writing speed dipped from 110MB/s to 65MB/s. However, the reading speed is not affected and remains near 111MB/s. Time taken for multiple files operation slightly increased. During the encrypted file transfer test, the CPU usage went up to 45%.

As for the performance difference between the Seagate IronWolf and Western Digital Red, I would say the different is marginal. This could be due to the number of disks in the RAID array. Perhaps a larger RAID volume of five Seagate IronWolf hard disks would make a difference?
