I'm on an Imac and I'm tired of having to constantly swap out all my external drives that use t3. I have a 40 dollar adapter for regular USB that I can have 8 different devices plugged into it but I cannot for the life of me find anything online that does that with thunderbolt 3 devices.

Am I missing a way to search for them on amazon or something? All I need is a basic 1 male to 2 (or hopefully more) female ends.

There's no such thing as a Thunderbolt "hub" - it doesn't work that way.

Instead, most thunderbolt devices should have two ports, to allow "daisy chaining" (i.e. connected in series to each other, rather than in parallel to a "hub" like with USB).

>doesn't work like that

Really? That's a huge bummer, I've been doing USB hubs for over a decade. How could it be that a new technology would take such a huge step backwards? Everything from usb to HDMI cables have hubs and splitters available.

And I have several external SSD and HDD drives that use t3 and none of them have an external port like that.

Pretty much all technologies have trade-offs to make.

USB uses a "hub" concept, Thunderbolt uses the "daisy chain" concept that Firewire and SCSI used.

Out of interest, what TB3 drives do you have, that don't have downstream TB3 ports on them? It's only usually portable devices or very high bandwidth devices (like eGPU cases) that don't provide the chaining port.

Thunderbolt ≠ USB

No version of Thunderbolt supports a hub topography. Thunderbolt is more like PCI bus; not really like USB. The confusing factor is that Thunderbolt 3 uses the same connector (but not cables) as USB-C.

Thunderbolt 1 and 2 used the same connector (but, again, not cables) as mini-DisplayPort, FYI.

There are, however, USB-C docks which have multiple USB-C ports on them, by the way.

Are your drives truly Thunderbolt 3 or are they USB-C??

It only took a year since you posted for someone to make something specifically for what you want.

Awesome! Any idea when it'll be available? Doesn't look like you can actually buy it there unfortunately.

System Requirements
  • Works with any Thunderbolt 4 PC
    • Windows 10 or later

Oh. That's a problem.

Look at the link I posted in the post above yours. OWC states that the hub will work with any Thunderbolt 3 equipped Mac that’s running 11.1 or later.

This page mentions the Mac compatibility: https://eshop.macsales.com/shop/owc-thunderbolt-hub
Of course, this is still a vaporware product, so there's always the possibility of issues coming up.
One of the big changes for thunderbolt 4 is support for hub-style connections. This is new and the OWC hub is one of just a few that are out now for this.

the Caldigit is another
