Thunderbolt 5 Dock Comparison:
Five High-End Docks Reviewed

iVANKY's FusionDock Max 2 and Ultra, CalDigit's TS5 and TS5 Plus, and UGREEN's Revodok Maxidok 17-in-1 — side by side on displays, USB-A count, Ethernet, built-in storage, and price. Whether you're running a 4-monitor creative setup, a home office, or a live trading desk, here's what actually matters once you get past the marketing spec sheet.

I'm currently running four external displays on my own trading desk — three high-end 5K monitors plus a 43" Samsung Frame TV pulling double duty as a dashboard. (You can see the full setup on my Trading Workstation page.) All four were already owned and repurposed for this desk, not bought new for it — which meant the real question for me wasn't "which dock has the most features," it was "which dock can actually drive four displays I already own, on the Mac I'm about to upgrade to, without paying for headroom I'll never use." That's the lens this comparison is written through, even though it's broadly useful for any 4-display Mac setup, trading or otherwise.

FusionDock Max 2 — Best Overall for Most Multi-Monitor Setups

All five docks here are capable Thunderbolt 5 hardware. The differences come down to what you're actually optimizing for: display count, USB-A peripheral support, built-in storage, or raw networking speed. For the most common case — driving 4 displays on an M5 Max MacBook Pro plus a full peripheral lineup — the iVANKY FusionDock Max 2 hits the best balance of price and capability. But three of the other four docks win outright for specific use cases, covered below.

Five-Way Head to Head
Before You Read Further — Platform Compatibility

Both iVANKY docks (FusionDock Max 2 and Ultra) are Apple Silicon–only — no PC, no Intel Mac, full stop. If you're on Windows or an older Intel-based Mac, the CalDigit TS5, TS5 Plus, and UGREEN Maxidok are cross-platform and the only three of these five actually available to you.

Spec Note — "4 Displays on M5 Max" Comes With Fine Print on Most of These

The FusionDock Max 2 natively supports 4 displays on M5 Max — either 3 downstream Thunderbolt 5 ports plus HDMI, or all 4 via Thunderbolt with one daisy-chained. The CalDigit TS5 and TS5 Plus also officially support up to 4 on M5 Max, but getting past the base dual-display config means using one of the dock's own spare Thunderbolt ports as an extra video pass-through — not a dedicated 3rd/4th output. Only the FusionDock Ultra's dual-chip design delivers all 4 without any of this. The UGREEN Maxidok is the clear exception in the other direction: capped at 2 displays on Mac regardless of chip generation, since its video output runs through only 2 spare Thunderbolt ports plus a DisplayPort 2.1 jack built primarily for Windows multi-stream setups.

From my own setup specifically: I'm running two LG UltraFine 5K displays plus an Apple Studio Display 5K through the Max 2 — three demanding 5K Thunderbolt displays at once. iVANKY's own site flags exactly this combination as a known edge case, recommending against pairing two LG/Samsung 5K panels together on this dock. That's likely why my setup needed a workaround, not a general limitation of the dock itself — worth knowing if your own setup leans on multiple high-bandwidth 5K monitors specifically.

* Reaching the 4th display on CalDigit docks requires using a spare Thunderbolt port for an extra video connection — see note above. ** USB-C port counts for both iVANKY docks are reported inconsistently across manufacturer listings and reviews, depending on whether Thunderbolt-capable ports are counted as dual-purpose USB-C; treat these as approximate.

Best Pick by Use Case
Max 2
Multi-monitor office, browser-heavy, or trading workloads
If your daily driver is displays, browsers, and SaaS dashboards rather than local storage or heavy networking, the Max 2 covers 4 native displays and a full peripheral lineup for $250 less than the Ultra — it just ties up 2 of the Mac's Thunderbolt ports to do it, rather than 1.
Ultra
You need every port and then some
26 total ports and native 4× TB5 display support with no adapters. Makes sense if you're routinely maxing out the Max 2's port count, but most setups won't get there.
CalDigit TS5
Quiet environment, minimal desk footprint
No fan at all — CalDigit relies on the aluminum chassis as a passive heat sink. Best pick if dock noise is a real consideration, or if 15 ports is genuinely enough for your setup.
TS5 Plus
Heavy peripheral use plus fast local networking
5 USB-A ports, dual USB controllers for simultaneous high-speed transfers, and 10GbE — the strongest all-around spec sheet here if your network actually supports multi-gig speeds.
UGREEN
You want the dock to double as external storage
The only dock here with a built-in M.2 NVMe slot (up to 8TB) — useful for video editing scratch disks or expanding a Mac with limited internal storage. The tradeoff is the 2-display cap on Mac, which rules it out for most 4-monitor setups.
The Trading Desk Case, Specifically

For a dedicated trading setup — multiple chart and dashboard displays, a browser-based broker platform, and accessory peripherals like a Stream Deck — the calculus narrows considerably. Two specs matter far more than the rest of the spec sheet: how many displays the dock actually drives, and how many Thunderbolt ports on the Mac itself get tied up doing it.

Rules Out
UGREEN Revodok Maxidok 17-in-1
The 2-display cap on Mac is a hard stop for a 4-monitor trading desk, regardless of how appealing the built-in SSD slot is for other use cases.
Overkill
FusionDock Ultra & CalDigit TS5 Plus
10GbE and dual USB controllers solve problems built for SSD arrays and high-throughput local networks — not a dashboard-and-browser trading workload. The Ultra's dual-cable upstream connection also ties up 2 Thunderbolt ports on the Mac instead of 1.
Best Fit
FusionDock Max 2 or CalDigit TS5
Both hit 4 native displays on M5 Max, but use the Mac's own Thunderbolt ports differently. The TS5 connects on a single cable; the Max 2 uses 2, leaving fewer of the Mac's own ports free for anything else. The Max 2 wins decisively on USB-A count (7 vs. 2) for keyboard, mouse, Stream Deck, and other peripherals without an external hub — worth the extra port if you need it; the TS5 wins if you're short on Mac-side Thunderbolt ports or want a silent, fanless desk.
Bottom Line

The right dock here isn't about avoiding the most expensive option — the TS5 is the exact same price as the Max 2, and the Ultra isn't even double. It's about matching what the dock actually does to what your setup actually needs. I went with the Max 2 because it covers what my desk needs today — enough USB-A for a full peripheral lineup, without paying for 10GbE or a dual USB controller I'd never touch. If your needs are genuinely different — more ports, faster networking, built-in storage — one of the other four is the better fit, regardless of price.
