The catch
Plugable TBT-UDH2
It has one downstream TB port. The rear ordinary USB-A and USB-C data ports run at 5Gb/s, and its exact host exclusions can rule it out.
Side by side
Plugable TBT-UDH2 vs CalDigit TS5 Plus compared: HDMI stays simple on UDH2, TS5 Plus serves a desk with 10GbE ready
Quick verdict
Two HDMI screens are the easy case for the TBT-UDH2, whereas the TS5 Plus is aimed at a desk that already has 10GbE. If your HDMI monitors and a 2.5GbE-or-slower network handle the job, the UDH2 is enough. A complete faster NAS path, more downstream TB connectivity or several permanent 10Gb/s USB devices make the case for the Plus. Host charging goes up to 140W on both. The Plus has no HDMI socket and needs its Windows Ethernet driver, and the UDH2 explicitly excludes older hosts, ARM and DP-MUX configurations.
Before you buy
Why, and what it costs you
Even with a fast NAS, the HDMI adapters may be the only change you notice
Say a household picks Plus for large photo or video backups but keeps its 2.5GbE switch and two HDMI monitors. In that arrangement the switch holds both docks to the same 2.5Gb/s link ceiling. Plus then needs compatible video conversion for the HDMI screens and never uses its faster network capability. UDH2 can be the simpler complete setup. Plus gets more convincing once the network path and NAS storage are ready, or when another Plus connection solves a separate need. That is why a dock should be priced together with the adapters and network equipment it requires, and why no backup-time saving should be invented from the 10GbE label.
Where this comes from
A stated 2.5GbE-switch bottleneck, plus direct-HDMI routes against adapter routes. min(10, 2.5)=min(2.5, 2.5)=2.5 Gb/s. No measured transfer time, price or universal conversion compatibility is claimed.
The catch
CalDigit TS5 Plus
There is no direct HDMI output. Its 10GbE advantage depends on the rest of the network, and Windows needs the stated driver.
Plugable TBT-UDH2
- Why pick it
- Your two HDMI monitors keep their present cables, you have one TB device, and nothing needs a network link above 2.5GbE at the dock.
- Your host appears on Plugable’s exact compatibility list, and fast USB devices can go in the suitable front ports.
- The catch
- It has one downstream TB port. The rear ordinary USB-A and USB-C data ports run at 5Gb/s, and its exact host exclusions can rule it out.
CalDigit TS5 Plus
- Why pick it
- A 10GbE NAS path that is ready would remove a real transfer bottleneck, provided you have checked the storage capability and Windows driver permission.
- Several permanently attached USB accessories need ports capable of 10Gb/s, or two TB branches plus DisplayPort fit your screen and drive layout better.
- The catch
- There is no direct HDMI output. Its 10GbE advantage depends on the rest of the network, and Windows needs the stated driver.

What this page compares
TBT-UDH2 vs TS5 Plus for dual HDMI monitors, a fast NAS and USB storage that stays plugged in. Look at hidden adapters and rear-port limits before you upgrade.
Each is a TB5 dock with 140W host power and a lot of desktop expansion. Someone building a permanent desk for work and creative projects can shop the two against each other, and the premium pick depends on the storage and monitor connections around it.

In practice
Differences you will notice
Even with a fast NAS, the HDMI adapters may be the only change you notice
Say a household picks Plus for large photo or video backups but keeps its 2.5GbE switch and two HDMI monitors. In that arrangement the switch holds both docks to the same 2.5Gb/s link ceiling. Plus then needs compatible video conversion for the HDMI screens and never uses its faster network capability. UDH2 can be the simpler complete setup. Plus gets more convincing once the network path and NAS storage are ready, or when another Plus connection solves a separate need. That is why a dock should be priced together with the adapters and network equipment it requires, and why no backup-time saving should be invented from the 10GbE label.
How we worked this out
A stated 2.5GbE-switch bottleneck, plus direct-HDMI routes against adapter routes. min(10, 2.5)=min(2.5, 2.5)=2.5 Gb/s. No measured transfer time, price or universal conversion compatibility is claimed.
Keeping the cabling neat at the rear can quietly change the storage path
A backup SSD that stays put is often plugged in at the back of the dock so the front remains free for phones and camera cards. UDH2’s ordinary rear USB-A and USB-C ports run at 5Gb/s, and its faster ordinary USB connections are on the front. Plus rates its ordinary USB data ports at 10Gb/s, so a compatible 10Gb/s SSD can stay on a suitable rear connection without that specific interface downgrade. It only matters when the drive and workload can go beyond the slower path. A hard drive, a low-speed accessory or an occasional small backup may gain nothing you would notice. UDH2 can still offer a faster front connection, which may be a perfectly acceptable cable trade.
How we worked this out
Exact rear ordinary USB interfaces at 5Gb/s versus 10Gb/s are weighed against permanent cable placement. A 10Gb/s-compatible SSD is a stated condition. There is no claim of doubled real throughput or a measured backup-time saving.
A laptop owned by your employer can turn the network upgrade into a question of permission
Plus needs its Windows driver for the 10GbE connection. If you use an employer-managed laptop for work and the same home NAS for personal media, find out whether that driver is permitted before the faster network becomes your reason to buy. On supported systems UDH2 documents operation without manually installed drivers, and its optional Ethernet update is a separate step for performance and support. That still does not make UDH2 compatible with every work laptop, because its TB3, USB-C-only, Windows ARM and DP-MUX exclusions apply. The better choice is the dock whose required setup is both supported and allowed. Do not buy around a permission that IT has not confirmed.
How we worked this out
Plus’s required Windows network driver is set against UDH2’s documented operation without manual drivers and its optional Ethernet update, all under a managed-device policy. No promise is made about any employer policy, automatic driver availability or an unsupported host.

Spec by spec
Where they really differ
| Spec | Plugable TBT-UDH2 | CalDigit TS5 Plus | In practice |
|---|---|---|---|
| HDMI desk | Two direct HDMI 2.1 outputs | No HDMI, with DP 2.1 and TB video routes | UDH2 lets you keep both HDMI cables with no extra conversion. |
| Downstream TB | One TB5 port, up to 30W | Two TB5 ports, up to 36W each | Plus gives you an additional direct branch, depending on the screen layout and host limits. |
| Local network | 2.5GbE | 10GbE with required Windows driver | The faster link is only useful once the whole switch and NAS route supports it. |
| Rear ordinary USB | USB-A and USB-C data ports at 5Gb/s | Ordinary USB-A and USB-C data ports rated for 10Gb/s | A drive that stays behind the dock for good can have a different interface ceiling. |
| Laptop power and cards | Up to 140W and UHS-II | Up to 140W and UHS-II | Capabilities both docks share are not enough on their own to change the screen or network plan. |
Trade-offs
What each pick costs you
With Plugable TBT-UDH2
- A fast USB SSD left on a rear ordinary USB port runs on the 5Gb/s interface. Moving it to a suitable front port may change how the cables are arranged.
With CalDigit TS5 Plus
- HDMI monitors need compatible adapters or video cables. Factor those in, along with any network changes, before you compare the complete setups.
Change of plan
When the answer changes
The HDMI and network arrangement you have is already enough
Go with Plugable TBT-UDH2. UDH2 keeps the equipment around it simpler.
A real limitation goes away with ready 10GbE or permanent fast USB connections
Go with CalDigit TS5 Plus. Once the host and driver requirements are met, Plus has a specific reason to be the upgrade.
Decision guide
Before you buy
Space for creative work and backups is what you are after, without adding monitor adapters for a network upgrade the rest of the home cannot use.
What this page can’t tell you
- There is no measured NAS or SSD speed advantage here, no universal guarantee about driver policy and no charging-time claim. Interface rates as supplied do not establish throughput when everything runs at once.
