Mobile Sync on DS918+

When snycing video’s for offline view via plex and ios (ipad), what’s the transfer speed for this? I own a DS412+ and transcoding is done by 1x, sometimes a bit more because it needs to transcode the files with subtitles. How fast is it with the newer models?

It depends on both the iPad model (what it’s capable of), speed of the LAN between the DiskStation and the Wifi, as well as the Wifi mode (b,g,n,ac)

I thought te bottleneck would be the synology and PMS, since transcoding is done by the server. Transferring the file to the iPad depends of course of the connection and the iPad…

Converting audio is a trivial task. Actual conversion typically runs at 10-15x realtime playback speed.
Transfer to the iPad is limited by networking and iPad receive speed.

That’s what I thought. So what are the average transcoding speeds on the latest NAS?

On a DS918+? I don’t keep track of the specifics. I can only suggest you hunt around the syno forum. there have been lots of reports for all forms of transcoding and other activities
