Single Client Throughput
HD Video Play - 720p HD stream from Windows Media Player, 256kB reads
HD Video Record - 720p HD stream, 256kB writes
File Copy from NAS - 4GB file copy, 64kB reads
File Copy to NAS - 64kB writes
Testing the 1019+, we have two additional Synology appliances for comparison. HD Video Playback gives a slight advantage to the 1019+ at 98.9 MB/s and moving to file copy operations we see 115 MB/s to the NAS and 83.7 MB/s from.
RAID 5 had the 1019+ coming in at 113 MB/s in File copy to and 57 MB/s from, 2 and 4x playback reached 114 MB/s and 92 MB/s respectively.
Last, we have RAID 6 giving us 81 MB/s in Playback and 112 MB/s for File Copy to and 65 MB/s from the NAS.
Benchmarks – Sequential Performance
Testing sequential performance of the 1019+, I added in both caching with two NVMe SSDs and Encryption. Starting with RAID 0, we see 116 MB/s read and 116 MB/s write as our baseline, no encryption or cache in use. Adding Encryption, we see performance drop to 115 MB/s read with no change to write performance. Offsetting the Encryption, we add NVMe cache and performance returns to 116 MB/s read and write.
The baseline for RAID 5 was the same 116 MB/s read and write. Adding Encryption and cache showed no difference in sequential performance, but we do see some changes in 4K Q8 and 32 as performance went from 3 MB/s to 60.6 MB/s with cache and 38 MB/s to 50 MB/s.
With RAID 6, we again baseline at 116 MB/s. Performance dipped to 112 MB/s read, and 111 MB/s write adding Encryption. Enabling the NVMe cache, we see performance bounce back to 116 MB/s. 4K shows similar with 66 MB/s as our baseline, while adding Encryption slows this to 2 MB/s. Adding in the NVMe cache, we get back to 58 MB/s.
Benchmarks – Workloads
Last, we have workloads with a broader comparison. RAID 0 showed a nearly identical performance curve to the 918+, the 1019+ slightly quicker.
The 918+ seems to take a performance advantage in Database and Web Server with the rest going to the 1019+ in RAID 5.
RAID 6, we see a more significant gap between the 918+ and 1019+ across the board.
