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.
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).

|Description||Seagate IronWolf||Western Digital Red|| Seagate IronWolf|
| Western Digital Red|
|Create 300 files of 20 kB (s)||1.1||1.3||1.6||1.7|
|Open/Close 300 files (s)||12.8||12.8||12.8||12.8|
|Remove 300 files (ms)||535.8||547.4||760.6||725.2|
|Lock/Unlock 16000 times (s)||6.3||6.2||6.9||6.8|
|Read directory (640 files) (ms)||28.7||28.7||33.8||36.3|
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?
