link aggregation between two NAS'?
I have a synology with 4 ports and a RN312 with 2 ports. Can I connect 2 ethernet cables directly between these 2 NAS' to speed up file transers to 2Gbps?
I bonded ports 3 & 4 in the Synology....

But how do I do it on the readynas? I can't access the readynas with both cables going to the synology. And if I leave just the one cable going to my switch and then bond the LANs I'm afraid I will then lose access to the Readynas. I am guessing I would then have to reset the whole thing?
What you need to do here is connect both NAS to a smart (or managed) switch, and then aggregate the links. Also connect that switch to your main network. A GS108Tv2 is one of several Netgear switches that you could use. These switches have their own Web UI, and you use that to configure the link aggregation on the switch (coordinating that with the NAS configuration).
As far as the bonding options go, you'd want to use either Round Robin in the ReadyNAS (with a static lag configuration in the switch), or LACP in both the ReadyNAS and the switch. I don't know what the aggregation modes are called in the Synology. If your goal is to speed up NAS->NAS backups, the static lag is better. LACP is designed to limit each data flow to 1 gigabit, so it won't improve the performance.
However, my advice is not to bother with any of this. If you have a lot of simultaneous users accessing the NAS, then link aggregation to the NAS can improve throughput. But home NAS users generally don't have much simultaneous access. And incremental backup speeds will be fast even over a single ethernet connection - likely less than half an hour to back up the Synology. So there isn't a lot of gain for most home NAS owners - not worth the hassle.
- Thanks for the swift response Steve. I only have an unmanaged switch. I was hoping the 4 ports in the synology would act as a switch. No? It's only me connecting. Most file transfer backups are in the realm of 30-100GB so I thought 2Gbps would be twice as fast. Appreciate the help.

If you are limited by the network speed, then 100GB should take 1000 seconds (about 17 minutes). If they are taking much longer than that, then link aggregation probably won't speed things up.
- Ok. I have been reading that people have been directly connecting from their pc to the 10GbE card in the nas and then using one of the four 1GbE ports on the nas to the switch (for pc internet and access to lan). So this got me thinking about all the variables. But I get it, 10GbE sounds like it's more about bandwidth than frequency.
I get a steady 111MBs on file transfers, which is fine but faster is always welcome. Though, it seems the more I read the struggle is real. Speed is going to be limited by the weakest link. Pc is reading from an ssd, so 500MBs, but the writing to the raid array on the nas I'm guessing will be the bottleneck here.
Appreciate the help and knowledge.
