Why a Thunderbolt 5 Dock Is a Smarter Spend Than Extra Storage or More Dongles

You’ve already spent over a thousand pounds on a MacBook Pro. Now you’re staring at the next purchase.

More storage? A better hub? A charger that actually hits full wattage? An SD reader for location shoots?

Most creators buy all of those things separately, one Amazon order at a time. A USB-C hub here. A portable SSD there. A GaN charger because the stock one isn’t fast enough. An HDMI adapter. An Ethernet dongle.

Each one solves exactly one problem and adds one more cable to the desk. By the time you’ve bought the lot, you’ve spent more than a Thunderbolt 5 dock would’ve cost, and you’ve got a drawer full of adapters fighting for the same three ports.

The maths on this is surprisingly one-sided once you lay out the prices.

Quick Takeaways

• A 10 Gbps USB-C hub plugged into a Thunderbolt 5 port uses only a fraction of the available bandwidth
• Buying a hub, SSD, charger, and adapters separately can easily exceed the cost of a single TB5 dock, and still leave you managing seven cables
• Apple’s internal storage upgrades are convenient and fast, but the incremental cost per GB is several times higher than an external NVMe blade
• A TB5 dock with a built-in M.2 slot replaces the SSD, the hub, the charger, and most of the adapters in one purchase
• Even using conservative local SSD speeds, working from local NVMe storage is orders of magnitude faster than uploading large project files over a typical UK home connection

How much do MacBook accessories actually cost when you add them up?

Most creators spend it in pieces and end up with a desk full of dongles that cost more than a single dock. A USB-C hub, a portable SSD, a faster charger, an HDMI adapter, an SD reader, and an Ethernet dongle. Add them up and the total creeps past £400 before you’ve noticed.

Let’s go over a realistic setup with prices. A mid-range USB-C hub runs about £40–£50. A 2 TB portable SSD like the Crucial X10 Pro or Samsung T9 costs around £150–£230 depending on the week. A 100 W GaN charger adds £40–£50.

Then the smaller bits: an HDMI 2.1 cable, a USB-C to DisplayPort cable, an SD card reader, and an Ethernet adapter. Each one is around £12–£25, and only adds another cable to the mix, along with another feature you need to give up.

That’s just if you go for the budget options. Real spending can quickly add up to so much more, plus delivery costs. The combined spend matches easily or exceeds a TB5 dock.

But what you’ve actually bought is six separate devices, six separate cables, and a hub that caps your data at USB 3.2 Gen 2 speeds (10 Gbps) while your MacBook Pro’s Thunderbolt 5 ports can handle up to 120 Gbps outbound.

How much of your Thunderbolt port are you actually using?

A 10 Gbps USB-C hub plugged into a Thunderbolt 5 port uses only a fraction of the available bandwidth. TB5 runs at up to 120 Gbps outbound. Most hubs top out at 10 Gbps. That’s like paying for a motorway and driving on the hard shoulder.

Intel’s Thunderbolt 5 specification delivers 80 Gbps bidirectional as the baseline, with a “bandwidth boost” mode that pushes 120 Gbps outbound for displays and storage. Thunderbolt 4 tops out at 40 Gbps. A standard USB 3.2 Gen 2 hub? 10 Gbps.

The difference shows up when you’re doing more than one thing at once. A dual 6K display setup, a fast NVMe transfer, and laptop charging can all run simultaneously on TB5 without throttling each other. On a 10 Gbps hub, something’s got to give.

For creators working with large files, the transfer-time comparison tells the story. Moving 1 TB of footage over USB 3.2 Gen 2x2 (the fastest USB standard most portable SSDs support) takes around 8–9 minutes.

Over TB5 with a PCIe Gen 4 NVMe drive, you’re looking at under 3 minutes, and you still have bandwidth left over for your monitors and ethernet.

Why doesn’t buying more storage fix the real problem?

Storage solves one thing: capacity. It doesn’t give you more ports, charge your laptop, or drive your monitors. And if you’re connecting it over USB 3.2 instead of Thunderbolt, it isn’t even that fast.

Consider the port arithmetic on an M4 Pro MacBook Pro. You’ve got three Thunderbolt 5 ports, an HDMI 2.1 port, an SDXC slot, and MagSafe. Connect an external SSD to one Thunderbolt port, a monitor to another, and your dock or charger to the third.

You’re full. No more ports for Ethernet, a second display, or an audio interface unless you start daisy-chaining or reach for a hub.

A dock consolidates all of those connections into one Thunderbolt cable.

A TB5 dock with a built-in M.2 NVMe slot (like the UGREEN Revodok Maxidok 17-in-1) adds up to 8 TB of PCIe Gen 4 storage inside the dock itself. You get the storage and the connectivity in the same device, through the same cable, without burning a second port on a separate SSD enclosure.

For video editors working with formats like Apple ProRes 4K60 422 HQ (which demands around 155 MB/s per stream) or Blackmagic RAW 6K (323 MB/s at 3:1 compression), the connection speed between your storage and your laptop isn’t academic.

Multicam timelines double or triple those data rates, and a USB 3.2 connection starts dropping frames before a Thunderbolt one does.

Is cloud storage actually cheaper than a dock?

Over three years, most cloud subscriptions cost more than a one-off dock purchase. Even using conservative local SSD speeds, working from local NVMe storage is orders of magnitude faster than uploading large project files over a typical UK home connection.

Let’s crunch the subscription costs.

iCloud+ at the 2 TB tier costs £8.99 per month in the UK, with no annual discount. Over three years, that’s just under £324.

Google One’s 2 TB plan runs £79.99 per year, or roughly £240 over three years.

Dropbox Plus (2 TB) comes in around £96 per year, or £288 over three.

All of those exceed the price of a mid-range TB5 dock, and at the end of three years, you don’t own anything.

Speed is the other problem.

Ofcom’s most recent published UK median upload speed is 18.4 Mbit/s (March 2023 data). At that speed, uploading 1 TB of footage to iCloud takes roughly five days.

Copying the same 1 TB to local NVMe storage through a Thunderbolt 5 connection takes under three minutes. Cloud is excellent for backup and cross-device sync. But you can’t scrub a Premiere Pro timeline from iCloud Drive, and you won’t be doing a multicam 4K edit from Google One.

What about the Apple storage upgrade?

Apple’s internal storage upgrades are convenient and fast, but the incremental cost per GB is several times higher than buying an external NVMe blade. Plus, Apple’s upgrade is locked to that one machine forever.

Check the Apple UK configurator for a MacBook Pro with M4 Pro. Going from 512 GB to 1 TB adds £200. From 512 GB to 2 TB adds £400. From 1 TB to 4 TB adds £460.

A 2 TB NVMe blade like a Crucial T500 or WD Black SN850X costs around £90–£120 at UK retail and installs straight into a Maxidok 17-in-1’s M.2 slot, running at PCIe Gen 4x4 speeds that reviewers have confirmed match internal SSD performance for most creator workflows.

The other advantage is portability across machines.

Apple’s storage upgrade is soldered in. When you sell that MacBook or upgrade to the next one, the storage stays behind. An NVMe blade in a dock’s M.2 slot lifts out in 30 seconds, and moves to whatever you’re using next.

For creators who upgrade every two or three years, that’s a meaningful difference. You’re not paying for storage you’ll leave behind.

Which UGREEN dock fits which setup?

Three docks, three use cases. The Mac mini creator, the mobile editor who docks at home, and the full studio build that needs every port with a built-in storage slot.

Mac mini M4 Pro creators: The Maxidok 10-in-1 Mac mini Dock sits directly under the mini, adds front-facing TB5 and USB-A ports, includes an M.2 NVMe slot, and drives dual 6K displays. It’s designed specifically for that machine and keeps everything in one footprint.

Mobile MacBook Pro editors: The Maxidok 10-in-1 TB5 delivers 100 W laptop charging, dual 6K display support, 10 ports, and Gigabit Ethernet through one cable. Sit down, plug in, and your entire studio setup is live. Unplug, and you’re out the door for a client meeting.

Full studio builds: The Maxidok 17-in-1 TB5 is the one with the built-in NVMe slot (up to 8 TB), 140 W laptop charging, 2.5 GbE, SD and microSD UHS-II readers, and 17 ports total. It’s the dock that makes the “dock vs storage” question disappear, because it’s both.

One thing worth knowing: the base M4 MacBook Pro and MacBook Air use Thunderbolt 4, not TB5. A TB5 dock still works with those machines, just at TB4 speeds (40 Gbps). That’s still 4x faster than a USB-C hub and enough for dual 4K displays, so it’s not a wasted purchase.

You’ll unlock the full TB5 speed when you eventually upgrade the laptop.

The dock-vs-storage debate is a false choice in 2026. A TB5 dock with an integrated NVMe slot isn’t just a connectivity upgrade. It’s the storage upgrade, the workflow upgrade, and the dongle-replacement programme in one purchase. One cable, one device, and your next £400 goes toward making your entire desk work better instead of just fixing one part of it.
