Head-to-head
CalDigit TS5 vs Plugable TBT-UDT3: TS5 leaves ordinary USB-C free, UDT3 keeps more USB-A plugs
The short answer
TS5 leaves ordinary USB-C accessory sockets free, while TBT-UDT3 keeps more USB-A plugs connected. Choose TS5 when two USB-C screens and a TB drive already occupy the three TB branches and other USB-C devices need to join them. Choose UDT3 when three USB-A plugs fit the remaining equipment better. Neither has fixed HDMI or DP outputs. Both supply up to 15W per downstream TB port, and UDT3 excludes Thunderbolt 3 hosts.
Before you choose
The reasoning and the trade-offs
Three screen-and-storage branches leave no USB-C socket for the evening accessories
Two compatible USB-C monitors and a TB drive can fill all three downstream ports on either dock. TS5 still has three ordinary USB-C data sockets for a phone, tablet or another compatible accessory. UDT3 does not. On UDT3, an appropriate A-to-C cable, suitable hub or direct laptop connection may solve the problem, so this is an extra-connection check rather than proof that the accessory cannot work. For a shared desk where different devices arrive after work, TS5 can preserve the permanent screen and storage wiring. If those accessories already use USB-A cables, UDT3’s extra A socket may be more useful.
What this is based on
Two display branches plus one TB-only drive exhaust three TB ports on both. TS5 has three additional ordinary C sockets, UDT3 none. Cable alternatives and device protocol remain explicit.
Main trade-off
Plugable TBT-UDT3
No ordinary USB-C accessory sockets beyond the three downstream TB ports. TB3 hosts are unsupported.
CalDigit TS5
- Choose it for
- Two supported USB-C screens and a TB drive use all three branches, while a phone or ordinary USB-C accessory still needs a separate socket.
- A supported Thunderbolt 3 Mac must remain in the setup. Verify its native display limits and the current CalDigit OS requirements.
- Main trade-off
- Only two USB-A sockets, including one USB 2.0. USB-C-only fallback loses Ethernet, and TB3 Windows is unsupported.
Plugable TBT-UDT3
- Choose it for
- Three USB-A accessories should stay connected, with two fast A sockets and one 5Gb/s socket covering the required connections.
- The host is supported TB5, TB4 or USB4, and the ordinary USB-C accessory plan does not need another branch.
- Main trade-off
- No ordinary USB-C accessory sockets beyond the three downstream TB ports. TB3 hosts are unsupported.
About this comparison
TS5 vs TBT-UDT3 for two USB-C screens, a TB drive and everyday accessories. Compare what stays free after the three Thunderbolt branches are occupied.
Both use three downstream TB5 branches, 140W host charging, 2.5GbE and UHS-II readers. They are close alternatives for a flexible USB-C screen setup, with a useful difference in the ordinary accessory connections.
Winner by situation
Start with what you need it to do
Two USB-C screens and a TB drive fill the three branches, with another USB-C device to add
TS5 keeps ordinary C sockets free. UDT3 needs another suitable route.

- Plugable TBT-UDT3
- Caution
Three USB-A plugs should stay connected directly
UDT3 has three A sockets. TS5 has two.

- Better fit
A supported TB3 Mac must also use the dock
TS5 supports qualifying TB3 Macs. UDT3 excludes TB3 hosts.
- CalDigit TS5
- Better fit
- Plugable TBT-UDT3
- Not suitable
A portable display needs more than 15W through its TB cable

What matters in practice
The differences that matter
Three screen-and-storage branches leave no USB-C socket for the evening accessories
Two compatible USB-C monitors and a TB drive can fill all three downstream ports on either dock. TS5 still has three ordinary USB-C data sockets for a phone, tablet or another compatible accessory. UDT3 does not. On UDT3, an appropriate A-to-C cable, suitable hub or direct laptop connection may solve the problem, so this is an extra-connection check rather than proof that the accessory cannot work. For a shared desk where different devices arrive after work, TS5 can preserve the permanent screen and storage wiring. If those accessories already use USB-A cables, UDT3’s extra A socket may be more useful.
How we reached this conclusion
Two display branches plus one TB-only drive exhaust three TB ports on both. TS5 has three additional ordinary C sockets, UDT3 none. Cable alternatives and device protocol remain explicit.
The newer connector plan can make an older webcam setup less convenient
A webcam, USB microphone and wireless keyboard receiver can mean three USB-A plugs before storage is considered. UDT3 accepts all three directly. TS5 has two A sockets, so one device needs a different compatible cable or another connection method. That does not mean the webcam, microphone and receiver all need 10Gb/s. The receiver may be perfectly suited to TS5’s USB 2.0 port. The issue is keeping the familiar devices connected without an extra hub. If the webcam or microphone has a replaceable USB-C cable, TS5’s ordinary C sockets can reverse the inconvenience. Check cable replaceability and device compatibility before choosing a dock around plug shapes alone.
How we reached this conclusion
Three explicitly assumed USB-A devices versus three UDT3 A sockets and two TS5 A sockets. No bandwidth or simultaneous performance assumption for those accessory classes.
A spare older Mac can matter more than the new laptop’s TB5 speed
A household may keep an older TB3 Mac for schoolwork or personal files while a newer work laptop uses the same monitors. TS5 documents TB3 Macsupport, with its current OS and display conditions. UDT3 excludes TB3 hosts. That makes TS5 the more useful starting point if both computers must use the dock, even though neither can turn the older host into a TB5 system. Verify the exact Mac and required screens rather than assuming every TB3 Macsupports the same arrangement. TS5 does not extend this support to TB3 Windows computers. A suitable cable cannot override an explicit unsupported-host boundary.
How we reached this conclusion
TS5 TB3 Macsupport versus UDT3 TB3 exclusion crossed with manual household host sharing. No universal display, charging or TB5-speed promise on the older host.

What changes the fit
| What changes | CalDigit TS5 | Plugable TBT-UDT3 | Why it matters |
|---|---|---|---|
| Downstream TB branches | Three TB5 ports, up to 15W each | Three TB5 ports, up to 15W each | The main screen-and-TB-drive topology is the same. |
| Ordinary USB-C accessories | Three separate USB-C 10Gb/s sockets | USB-C accessories use the downstream TB ports | TS5 can keep the TB branches for screens and TB devices. |
| USB-A accessories | One 10Gb/s plus one USB 2.0 socket | Two 10Gb/s plus one 5Gb/s socket | UDT3 can retain three A-shaped plugs without another hub. |
| Fixed HDMI or DP | None | None | Both need compatible video adapters for those monitor inputs. |
| Older Thunderbolt Mac | TB3 Macsupported under stated OS and host limits | TB3 hosts unsupported | A second household computer can decide which dock is usable. |
| Host power, network and cards | Up to 140W, 2.5GbE, UHS-II | Up to 140W, 2.5GbE, UHS-II | Shared headline features are not a reason to prefer one without an actual connection need. |
What you give up
Every choice has a cost
If you choose CalDigit TS5
- More than two retained USB-A plugs need a suitable cable change, adapter or hub. Do not buy extra bandwidth for a keyboard receiver that does not need it.
If you choose Plugable TBT-UDT3
- When screens and storage fill all three TB ports, another USB-C device needs a suitable A-to-C cable, hub or host connection.
Recommendation switch
The decision flips if...
Ordinary USB-C accessories or a supported older Mac are part of the real setup
Choose CalDigit TS5. TS5 covers those conditions beyond the shared three-branch layout.
Three retained USB-A plugs matter and every host is supported
Choose Plugable TBT-UDT3. UDT3 provides the more convenient A-port arrangement.
What matters in practice
Before you choose
You want three flexible Thunderbolt branches without using them up on the phone, webcam or older accessories that arrive after the screens and storage.
What this comparison cannot tell you
- No speed or stability winner. Three downstream ports do not promise three native external displays. Host power and downstream accessory power are separate.
