Media Performance
Single Video Playback
This test reads a single 2GB file from the device. The file is read sequentially in 256 kb blocks. That simulates a 720p HD video streamed over the network.
Dual Video Playback
This is the same test as before, only this time there are two HD Video Playbacks at the same time. This simulates streaming to two different media players at once.
Quadruple Video Playback
In the same way that the 2x Video Playback streams to the equivalent of two external media players at the same time, the test here doubles up on that to a four-player simulation.
Video Recording
The HD Video Record test is, as the name suggests, a test where we write to the NAS box. It writes a single 2 GB file in 256 kB blocks sequentially to the device.
Combined Video Playback and Recording
The HD playback and record test performs the same single record and playback tests as before, but simultaneously. This test is a good way t show how the system performs with quick changes between reading and writing two large blocks of data across the network to the device.
I noted in most of the recent 1-bay and 2-bay Synology home models (119J, 218Play, 218J) the office performance is much slower compared to much older models such as the 216J, 115J, etc. Is this due to the ARM processor that runs on these models or a change in how it was benchmarked?
I currently have a 120J and 218J, and noted that they seem to be struggling in two areas,
1. Indexing photos and videos (takes so much time)
2. Does not have transcoding, but my client player an Android TV with very decent hardware and Chromecast (does not play all formats) seems to handle this issue
I planned to replace my 120J with 218+ (cannot go up the food chain due to budget limits) since this has a dual-core Intel processor that might work better in Photo indexing and has some Transcoding capabilities if i required to use. The photo indexing performance is what is important to meas it takes ages to view images thumbnails.
