The first MacBook Pro I purchased for myself was in 2016. It was the year the “dongle era” was launched, and everyone had to switch their way of working to include docks and hubs. Ever since then, a docking station has been a part of my workspace. I work from home, but my primary computers are both MacBook Pros. I connect to an external monitor, keyboard, mouse, and webcam, all of which are wired through a docking station. Then, the swap between the two computers becomes simple. I just unplug the host cable from one and into the other. Thunderbolt has made that swap very easy because it is fast and there is no lag when I swap the systems.
For the past couple of years, my main docking station has been the CalDigit TS4, which has become somewhat of a “gold standard” because of its stability, large port selection, and superior macOS support. It’s been a reliable companion for my MacBook Pro-driven setup, but with Thunderbolt 5 emerging into the marketplace, I thought it might make sense to see about an upgrade, and that’s what led me to the StarTech Thunderbolt 5 Universal Docking Station.
I knew I wanted something with a similar form factor to my previous dock and the StarTech 215N-TB5USB4DOCK delivers the major advantages of Thunderbolt 5, including high-bandwidth display support, 140W charging, and fast data transfer speeds, while providing a stable workstation experience.
With that said, let’s dive into the StarTech Thunderbolt 5 Universal Docking Station.

User Experience
First of all, let’s talk about the design of this docking station. My MacBook Pro is Space Gray, and the finish of the StarTech dock is very close to that color. So, it automatically gets points with me for looking like an Apple-oriented product. The size is perfect for my more compact workspace (I have the CORSAIR Platform:4 desk, which is 47” in length). With less desk real estate, having a smaller form dock is essential to keeping my desk neat and orderly. The StarTech dock fits the workspace like a glove.
Getting it set up was very easy. There was no software to install or drivers to update in order to get the maximum performance from the dock. I just powered it on and connected everything I wanted to it. Here’s my setup.
2024 14-inch MacBook Pro M4 (connected via Thunderbolt 4) LG 34” UltraGear WQHD 240Hz Curved Gaming Monitor (connected via DisplayPort) Razer Deathadder V4 Pro Mouse (connected via USB-A) Kensington W1050 1080p Webcam (connected via USB-A) Razer Deathstalker V2 Pro keyboard (connected via USB-C)In addition to my main devices listed above, I also tested the dock using a 2024 16-inch MacBook Pro M4 Max, which provides Thunderbolt 5 connectivity.
I was able to connect everything to the back of the dock, but this did take up all the ports. In fact, I have a light bar that I had plugged in through my previous dock, and I had to plug it into the back of the monitor instead.
Now, I want to point out that I realize that my model MacBook Pro only supports Thunderbolt 4, but upgrading to a Thunderbolt 5 dock still benefits my system through strong display handling, 140W charging, stable peripheral connectivity, and, of course, future-proofing, which was my main goal with the upgrade. With my specific workflow/setup, I’m not missing much limiting the output of the StarTech dock to Thunderbolt 4.
The main limitation is reduced overall bandwidth headroom, meaning I am not able to take full advantage of Thunderbolt 5’s expanded capacity for running multiple high-bandwidth devices at the same time, such as several high-resolution displays, fast NVMe storage arrays, 10GbE networking, or multiple demanding peripherals simultaneously. My current setup does not push anywhere near those limits, and all key functions including my ultrawide 240Hz display, USB devices, Ethernet, and charging remain fully stable and responsive in day-to-day use.
So far, I’ve been extremely happy with the dock’s day-to-day performance. I haven’t noticed any bottlenecks, and it seems that my peripherals are behaving more consistently, with faster wake responsiveness, stable connections, and no noticeable dropouts even during heavier multitasking and sustained use.
When it comes to testing, I was looking at a couple of specific areas.
External monitor stability & compatibility Wake/Sleep behavior Charging performance & Thermal Behavior Data transfer (flash drives, external SSDs, etc.)Even though this is compatible with systems other than macOS, that is my primary use case and my main focus for testing since I’m testing the overall compatibility of the StarTech dock with macOS.
External Monitor Connection
External monitor stability and refresh rate support were solid throughout testing. I verified resolution and refresh rates on my LG 34-inch UltraGear WQHD 1440p 240Hz (34G630A-B). The monitor is connected to the dock using a DisplayPort cable, and the laptop is connected to the dock using the Thunderbolt 5 cable that was included. The connection has been reliable with no flickering, black screens, or signal drops. I confirmed the refresh rate using the UFO test in Chrome, which correctly showed 240Hz, and that result makes it clear the StarTech dock is handling the LG monitor extremely well. This was verified for both Thunderbolt 4 and Thunderbolt 5 connections.
Wake/Sleep Behavior
Wake and sleep behavior has also been strong. The MacBook Pro wakes up very quickly from sleep, especially when running in closed-clamshell mode, typically coming back online in just a few seconds. The LG display reconnects quickly and consistently, and overall wake performance feels faster than what I experienced with my previous dock. I did not see any issues with USB devices failing to reinitialize, and everything came back online without intervention.
Charging Performance & Thermal Behavior
Charging performance has been consistent with no issues. The dock has no problem keeping the MacBook Pro and connected peripherals powered while in use. I also verified that it maintains stable charging while simultaneously running displays and multiple accessories, and everything remained stable during extended sessions. The 16-inch MacBook Pro, which requires a 140W power adapter, charged normally while connected to the StarTech dock as did the 14-inch MacBook Pro, which only needs 70W.
In terms of thermal behavior, after several hours of continuous use, the top of the dock felt warm, but it was still under 100º on the surface when measured with an infrared thermometer, which is well within a normal operating range.
Data Transfer
The front-facing ports on the dock are designed to deliver solid high-speed performance, with both USB-C 10Gbps and USB-A 10Gbps ports handling fast external drive transfers and accessory connections. The SD and microSD UHS-II (SD 4.0) card readers also provide strong real-world speeds for media offloading, making them reliable for quick transfers from cameras and other portable devices.
Using both laptops, I tested a variety of external storage devices with these ports using Blackmagic Disk Speed Transfer’s stress tests. I used multiple stress levels to get a clearer picture of both peak and sustained performance. By comparing results across different stress levels, it becomes easier to see whether performance remains consistent under load or if speeds begin to taper off once the initial cache is exhausted. Here are the results. The device that was tested and the port it was used on is indicated.
PNY Elite-X Type-C USB 3.2 Gen 1 Flash Drive • USB-C 10G port

Yes. The USB-C 10Gbps port is not acting as a bottleneck, as the performance changes between the 1GB and 5GB tests reflect typical flash drive caching and sustained write behavior rather than any limitation of the dock. The variation in speeds is driven by the storage device itself, and the dock is performing within its expected specifications.
WD MyPassport SSD (WDBAGF0010BGD) USB 3.2 Gen 2 • USB-C 10G port

Yes. These results are generally expected for a USB 3.2 Gen 2 SSD connected through the dock’s 10Gbps USB-C port. The significantly higher 1GB write result appears to reflect short-duration burst performance and caching behavior, while the 5GB stress test provides a more realistic view of sustained transfer speeds. Overall, the dock is performing within expected specifications, and the results indicate that the USB-C 10Gbps port is not acting as a bottleneck.
SanDisk Extreme PRO 200 MB/s SDXC V30 I • SD Card Slot
Thunderbolt 4WRITE (MB/s)READ (MB/s)1GB Stress Test200.6169.15GB Stress Test138.9170.5 Thunderbolt 5WRITE (MB/s)READ (MB/s)1GB Stress Test161169.25GB Stress Test139.7169.4Are these expected results?
Yes. The SanDisk Extreme PRO V30 card is rated for up to around 200 MB/s read speeds, so the 1GB test reaching ~200 MB/s aligns with its peak performance under ideal conditions. The drop in write speed during the 5GB stress test is also normal and reflects sustained write behavior once the card’s internal cache is saturated. Read speeds remain stable across both tests, which is typical for this class of SD card. Overall, the dock’s SD slot is performing as expected for a UHS-II reader, and the results are consistent with the limitations of the card rather than any bottleneck in the dock.
SanDisk Extreme Micro SDXC V30 I • Micro SD Card Slot

Yes. The SanDisk Extreme microSD V30 card is capable of near its rated performance in short burst scenarios, which is reflected in the higher 1GB test results. The lower write speed during the 5GB stress test is normal and indicates sustained write performance after the card’s cache is filled. Read speeds remain consistent across both tests, which is typical for this class of microSD media. Overall, the dock is performing within expected specifications, and the variation in results is driven by the microSD card’s sustained performance characteristics rather than any limitation of the dock’s card reader.
PNY 128GB Turbo Attache 3 USB 3.0 Flash Drive with USB-A adapter • USB-A 10G port
Thunderbolt 4WRITE (MB/s)READ (MB/s)1GB Stress Test54115.75GB Stress Test36.1212 Thunderbolt 5WRITE (MB/s)READ (MB/s)1GB Stress Test27.335.95GB Stress Test15.236Yes. The performance here is limited by the PNY Turbo Attache 3 flash drive rather than the dock. The drop in write speed from the 1GB to 5GB test reflects normal cache exhaustion and sustained write behavior, where performance falls to the drive’s true long-term limits. The variation in read speeds between tests is also typical for lower-end flash controllers under different caching conditions. Overall, the dock is operating within expected specifications, and performance is consistent with the limitations of the flash drive rather than the USB-A port itself.
NOTE: When it came to testing the USB-A port, I ran into some issues. Several USB-A flash drives could not complete the 5GB stress test. An error stating that the test file could not be written would appear and I would switch to a different drive. After 3-4 flash drives, I switched to a USB-C flash drive, the PNY Turbo Attache that I previously tested with the USB-C port, and connected it using a USB-A adapter. The adapter isn’t clearly labeled, but it is at least USB 3.0.
The PNY flash drive ended up working, which led me to believe that the earlier issues were likely caused by the other flash drives themselves and their internal controller or storage conditions rather than any limitation or instability with the dock’s USB-A port.
Final Thoughts
Overall, this feels like a meaningful upgrade in my setup, particularly in day-to-day performance and overall responsiveness rather than just raw specifications. The dock has been consistently stable with my MacBook Pro in clamshell mode, and everything from display output to peripheral reconnect behavior has felt faster and more reliable compared to my previous workflow. I have not run into any real-world bottlenecks in my current workflow, and the dock handles everything I throw at it without hesitation. In that sense, the StarTech dock feels like a practical improvement in everyday usability.
