Synology DS415+ and Link Aggregation

Hi,

I saw some topics on this forum about Link Aggregation.

I have several questions.

1. Can it be motivated to buy a Netgear GS108TV2 that enables me to do Link Aggregation?

2. What will be the difference in performance (besides being faster, my content is a mix of 720p & 1080p)? (I have now a 5 port Netgear gbit switch).

3. Will PMS still work? (I saw some users on the forum having some problems with LAG).

Thanks in advance
