At the moment I have a MacBook Pro 16 connected to an 8TB and a 4TB ThunderBlade V4 via a TB3 chain, so both drives taking up one TB3 port on my computer.
MacBook > TB3 > 8TB Drive > TB3 > 4TB Drive
I backup the above drives to my NAS via a 10GBe ThunderBolt 3 adapter.
At the moment the 10GBe adapter connects to the opposite side of my MacBook (so separate bus) and I use this to backup the above drives. The drives are used for video editing so as you can imagine, they contain large project files and I can be backing up 150GB at any one time.
So, my current data flow for a live backup is as follows:
Editing drives on chain > TB3 > MacBook > Opposite side TB3 > 10GBe adapter > 10GBe Switch > 10GBe NAS
This seems to work quite well. I can backup 150GB of data in around 5 minutes.
However, I'm wondering if it would be better to connect the 10GBe adapter to the existing chain that the editing drives are on?
So the proposed setup would be:
Editing Drives > 10GBe Adapter > 10GBe switch > NAS
This would remove the MacBook being in the middle.
My question is, if I was to transfer data in this new way, does the data pass from the drive directly to the 10GBe adapter and onwards down the same chain?
Or will the data still pass from the drives, to the MacBook, then back down the same interface and further down the chain, which is, in my case, less efficient than my current setup.
In other words, is it smart enough to pass data from one device to another on the same chain, or does it still pass data through the connected MacBook and back down the chain to the destination?
