OWC Thunderbolt 4 Dock Review: 8.7/10 - The Pro Connectivity Standard
Overview
The OWC Thunderbolt 4 Dock delivers 11 ports including three downstream Thunderbolt 4 ports, 2.5G Ethernet, SD 4.0 card reader, and 96W laptop charging in a compact aluminum chassis. At $199, it’s the most versatile Thunderbolt 4 dock under the CalDigit TS4’s $379 price point.
Design & Build
OWC’s dock uses an anodized aluminum enclosure that matches the Mac aesthetic perfectly and acts as a heatsink - the dock is always warm to the touch but never hot. The dark gray finish resists scratches well. At 8.5 inches wide, it takes up more desk space than a dongle but sits flat with rubber feet that prevent sliding. The front panel includes the SD 4.0 slot and 3.5mm audio jack for easy access, while all Thunderbolt and USB ports are on the back. The included 0.8m Thunderbolt 4 cable is adequate for desktop use but short for under-desk mounting.
Performance
Thunderbolt 4 delivers consistent 32Gbps sustained throughput in our Blackmagic Disk Speed Test with a Samsung 990 Pro NVMe enclosure - enough for 8K ProRes RAW video editing directly from external storage. The three downstream Thunderbolt 4 ports support daisy-chaining up to five devices and deliver 15W each for bus-powered devices. The 2.5G Ethernet port achieves 2.36Gbps throughput with a 2.5G switch - sufficient for large file transfers on fast NAS setups. The SD 4.0 UHS-II card reader reaches 310MB/s read and 280MB/s write with V90 cards, matching the fastest internal readers. The USB-A ports deliver 10Gbps each, not just 5Gbps.
Features
The 96W Power Delivery charges a 16-inch MacBook Pro or Windows workstation at full speed while leaving the laptop’s own ports free. The 180W power supply provides 84W headroom for connected peripherals. Display support includes up to two 6K displays (60Hz) or a single 8K display via a downstream Thunderbolt port. The dock supports all Thunderbolt 4 security features including Intel VT-d and DMA protection. The 3.5mm audio jack supports headset mic input via CTIA standard. The lack of HDMI or DisplayPort outputs means you must use Thunderbolt-native displays or USB-C to HDMI adapters with downstream ports.
Pros
- Three downstream Thunderbolt 4 ports for daisy-chaining
- 96W laptop charging with 180W total power supply
- SD 4.0 UHS-II card reader at 310MB/s
- 2.5G Ethernet for fast NAS transfers
Cons
- No dedicated HDMI or DisplayPort outputs
- 0.8m Thunderbolt cable is short for desk routing

Verdict
