Can extra RAM or eSATA SSD improve Plex transcoding on Synology ds218+?

[ed]

No RAM upgrade will not speed up transcoding. But having one of the bays with SSD or even external esata SSD could speed things up slightly. One you store media on the SSD, it is much quicker for a NAS to find the movies on related metadata as well as temp files. Therefore you get smoother user experience.I hope this helps.
