Thanks everyone.

I am using Teracopy now, which is allowing me to quickly create a backlog of file transfers, so that I can do something else while it chugs along.

So this thread has been useful to me at least.

Just out of curiosity, with my current setup...

>

The dotted pink line is a possible path where I can connect 1 NAS NIC directly to the router (or Edimax) if that would be of any benefit other than failover.

When copying data in and out of the NAS via the Win10PC, which path will the data be taking?

To the TL-SG108 and back?

To the SG-1016 and back?

To the VF UltraHub and back?

Thx.

EDIT: Woah that pic is big! Sorry.

You will still create a broadcast storm by connecting that up, id get a managed switch and create a LAG/Trunk group and bond both your Win10 PC and your NAS to get 2GBPS

the key component you are missing is the managed switch

This is NOT correct!
You will NOT get 2gb between 2 single devices.
With link aggregation
(They are limited to 1port(1gb) per device)

You need 4 separate devices connecting to a 4gb link aggregation to get up to 4gb performance.

Data path = Drobo --> TL-SG108 --> win10 PC --> TL-SG108 --> Drobo.

If you add a 2nd link on the 'pink line' - you are 'multi-homed' and create conflicting data paths (broadcast storm - as the two different data paths fight for sepremacy & 'drown out' and overload ALL network traffic.)
[- unless you have a high end switch designed to identify this situation & block it from happening.]
(Note: You don't have a high end switch with this capability)

That's why you shouldn't add a 2nd link.

EDIT : I do have a TP-LINK TL-SG108PE which I bought when I was thinking about getting some PoE stuff, but didnt, would it work?

the TL-SG108PE is a 4x PoE + 4 eth EASY (managed) switch and can do VLANs and LAGs (but not LACP). So this explains maybe the "missing storm" ;-)

(SG108PE and SG108E are capable, SG108 not). If PoE is not linked to a PoE splitter on a relevant port, the switch goes automatically back to normal (nonPoE) eth port.

The Edimax GS-1016 is a 'thumb' switch and I'm not sure why you use it except putting it to an own LAN/VLAN switchport of the SG108PE (i.e. with a SINGLE 1G/b cable). What you can achive with a 2port LAG is fault redundancy if one port of your Drobo fails and/or load balancing, but not doubling the bandwith (in this combo, as stated before by several posts).

- SRV: 12 RU HA server cluster, 0.1 PB storage on premise
- IoT: thread, zigbee, tasmota, BidCoS, LoRa, WX suite, IR
- 3D: two 3D printers, 3D scanner, CNC router, laser cutter

I have the Edimax (yes it is a GS-1016, oops) as it is a 16 port switch that fits in the weeny rack on a shelf in the closet.

The TL-SG108PE is still in its box. Never used.

So I'm hearing to also only use 1 NIC on the Drobo??

I have realised that there is nothing I can do to increase the speed of the data, but I can improve my workflow to make it less onerous.

Yes indeed. If you are not dependent of the 16 port count of the Edimax, I'd replace it with the 8port smart/easy manageable TL-SG108PE since this unit is more likely supporting you in terms of further learning of network technology. You can start just by replacing the Edimax (without any change in the switch config and as it comes out of the box). This is neutral behaviour of the switch. One thing you could do is to change the default IP address to the relevant address determined by your vodafone router/box to have the opportunity to reach the switch's web interface - but not mandatory for the first. Then plug it in, find out what the switch is useable for and you quickly find the gaps of your network equipment for LATER improvment (without making the switch completely obsolete - it's just further development when you expand your needs). Maybe you find out that you like to replace the vodafone router because it COULD (I don't know) lack of VLAN capability but you feel you want it due to the increasing IoT stuff. Then you can make further decisions what's next to be replaced/upgraded or to head to next.
