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 write test 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 to show how the system performs with quick changes between reading and writing two large blocks of data across the network to the device.
