Buyer’s guide comparing CalDigit’s Thunderbolt Station lineup — TS4 (TB4), TS5 (TB5), and TS5 Plus (TB5 + denser I/O / 10GbE). Specs from CalDigit and Amazon listings; not a lab bandwidth test.

Best for: Shoppers stuck between “keep TS4” vs “jump to TB5” vs “pay for TS5 Plus ports/Ethernet.”
Not for: Travel palm hubs; Dell ExpressCharge fleets (buy Dell docks); base Apple Silicon users hoping any CalDigit invents a second native display.
Short answer: Buy the CalDigit TS4 if your laptop is still Thunderbolt 4, the TS5 if you have Thunderbolt 5 and do not need 10GbE, and the TS5 Plus only if you need the denser ports and 10GbE.
FAQ
Should I replace a CalDigit TS4 if my laptop does not have Thunderbolt 5?
No. On a Thunderbolt 4-only computer, TS5 money mostly buys bandwidth you cannot fully use yet, and the TS4 remains the desk default.
Who should buy the CalDigit TS5 instead of the TS5 Plus?
Buy the TS5 for a first Thunderbolt 5 CalDigit desk when you do not need 10GbE or the extra ports on the Plus.
Who is the CalDigit TS5 Plus for?
Editors and engineers on Thunderbolt 5 hosts who move large files over 10 Gigabit Ethernet. It is not the pick for a travel bag or a basic dual-1080p desk.
Quick answer — who should buy which
- Buy TS4 if your Mac/PC is still Thunderbolt 4 / USB4@40Gbps and you want the mature 18-port desk default. Deep dive: CalDigit TS4 review.
- Buy TS5 if your next host has Thunderbolt 5 ports and you want CalDigit’s modern 15-port / 140W desk without the Plus premium.
- Buy TS5 Plus if you need the denser 20-port layout and PCIe-class 10GbE (or you are building a long-horizon TB5 workstation budget).
- Skip all three if you only need HDMI + a few USB ports in a bag — see travel hubs instead.
Spec snapshot
| TS4 | TS5 | TS5 Plus | |
|---|---|---|---|
| Host link | Thunderbolt 4 (40Gb/s) | Thunderbolt 5 (80Gb/s) | Thunderbolt 5 (80Gb/s) |
| Ports (marketing) | 18 | 15 | 20 |
| Typical host PD | ~98W | ~140W | ~140W-class (check SKU PSU) |
| Ethernet | 2.5GbE | 2.5GbE | PCIe 10GbE class |
| Best host | TB4 Mac / Windows desks | New TB5 laptops | TB5 desks needing max I/O + 10GbE |
| Value play | Still the TB4 king | CalDigit TB5 “standard” | Premium future desk |
1. CalDigit TS4 — keep if TB4 is enough
The TS4 remains the “stop researching” Thunderbolt 4 dock: 18 ports, 98W PD, 2.5GbE, UHS-II readers, and a huge installed base. If your laptop does not have Thunderbolt 5, spending TS5 money mostly buys ports and bandwidth you cannot fully use yet. Full write-up: TS4 review.
Best for: M-series Pro/Max dual-display desks, Windows TB4 workstations, photographers who live on SD + 2.5GbE.
Not for: Buyers whose next refresh is clearly TB5 within months and who want one cable forever — they should shortlist TS5/Plus instead.
2. CalDigit TS5 — the TB5 successor
TS5 is CalDigit’s mainstream Thunderbolt 5 desk: four TB5 paths, ~140W charging, dual 8K@60 marketing claims, and the familiar Space Gray brick. Pair it with a TB5 host (newer Windows Intel Core Ultra class / Macs with TB5). On a TB4-only MacBook it will usually fall back — you paid for headroom you are not using.
Best for: First TB5 desk purchase when you do not need 10GbE or the Plus port count.
Not for: Anyone happy on TS4 today with no TB5 host on order.
3. CalDigit TS5 Plus — max ports + 10GbE
TS5 Plus stretches the lineup toward “buy once for a decade” desks: ~20 ports and PCIe-class 10 Gigabit Ethernet. Pay the premium when wired 10GbE to a NAS/switch is weekly work — not when you just want HDMI and USB-A for Slack.
Best for: Editors, engineers, and lab desks moving large files over copper Ethernet on TB5 hosts.
Not for: Dual-1080p productivity or travel bags.
Decision tree
- Host is TB4-only and desk is stable → TS4.
- Host is (or will be) TB5 and you want CalDigit without 10GbE → TS5.
- Host is TB5 and you need denser I/O / 10GbE → TS5 Plus.
- Unsure about TB5 timing → read Is Thunderbolt 5 worth it? then default TS4.

Keep comparing: MacBook docks (M1–M5) if the host is Apple Silicon and display count is the real question. Disclosure: As an Amazon Associate I earn from qualifying purchases. Product cards and outbound Amazon links are affiliate links. Tag: onsight068-20.
