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....
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.

No, they won't act as a switch (and with the ReadyNAS there is no connection sharing, so you can't access a NAS over your home network when when it is directly connected to another NAS)
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.

But if you want to get the best performance with link aggregation, just get a smart switch - ideally one that has enough ports to connect all the ports in all your devices. You can get an 8 port smart switch for about $60 US, and get a 16 port one for about $120.

Faster speeds are certainly possible. But you'd need something faster than gigabit ethernet running in at least one of your PCs to be make much use of it.
FWIW, I see 500-600 MB/s speeds with NAStester on my own setup. That's between a PC I use as an application server and my RN526x. Both are equipped with 10 gigabit ethernet and are connected through a small 10 gigabit switch. The NAS uses 4x6TB RAID-5 with WD60EFRX disks.
10GBase-T is still too expensive for me to put everywhere (and laptops don't have it). So our other PCs all run gigabit ethernet, and they are limited to ~100 MB/s (and of course less when using WiFi).
- I assume u get 500-600MB in actual transfers? This is good to know. Maybe I will start off with LAG this way I can use it with the RN316 if/when I go 10GbE.
What do u recommend for a NIC for the pc? Some of the dual nic cards are almost the same cost as the 10GbE nics.
