any Thunderbolt 3 users? cheap way to test connection?

Recommended Posts


Not knowing where to post this, so, I thought I'd try here.

Before I buy expen$ive Thunderbolt 3 devices, what would be a cheap way to test the Thunderbolt 3 connection?

Wanting a mega RAID 10 NAS.
Testing a new to me PC build with windoze10 pro.
Luckily, my Resolve Studio dongle is legit, it works coming from the older Win7Pro station.
ASRock Z370 Killer SLI/ac - 8700K - Zotec 2080 - only 16GB right now...
ASRock Thunderbolt 3 AIC is at the PO, I missed the delivery today.
I've read many other forums this combo works, even with Hackingtosh builds.
Wanting a cheap way to test the communications protocol first...

What kind of monitor you have? Isn't a Thunderbolt 3 port usable as a Display Port? No I/O data, well it would show output, not input, but you would know it is active.

USB 3.1 can also be used as displayport, but only has 10Gbit/s transfer rate compared to Thundersbolts 40Gbit/s. I would therefore image the issue is how to test if the connection has the full 40Gbit/s capabilities. I have no solution for this, but I would mention that USB-C/Thunderbolt has been a somewhat unreliable technology from my experience.

I have this kind of setup to connect my 4K Dell to my MBP via a cable.

In terms of testing it beforehand, I'm not sure how you would do that, but I also think that maybe you don't need to.  If you get the RAID setup and it doesn't work with the ASRock Thunderbolt 3 at 40Gb/s then just return the ASRock and get something else that does work.  Even if you have to bin it and buy another Thunderbolt card, you'd still lose less than buying your second RAID choice.

Thunderbolt can be used for a LOT of things.

Thunderbolt 3 is 40GB/s data stream.

Yo9u can daisy chain devices.

Why would you suspect your Thunderbolt doesn't work?? If in doubt, buy your RAID in a place where you can return it.

You make it seem like Thunderbolt3 performance is predictable.

Here is one example of how unpredictable it can be: The left side Thunderbolt3 ports on a 2017 MacBook Pro Touchbar has higher bandwidth than the right side Thunderbolt3 ports.

I want an external GPU, but it seems like the only way to find out how well it will work on your specific configuration is to test it yourself.

Seems to be working.

I got a Dell Business Thunderbolt 3 Dock - TB16 from IT at werke to use over the weekend.

All is working okay, monitor ports, etc...

Cool.

I didn't knew, I have Thunderbolt 2 and use it as video output. It's not good news then Thunderbolt 3 performance is finicky...
