The Past, Present, and Future is Yours
Connect to past, present or future Thunderbolt and USB devices with the OWC Thunderbolt Dock’s three Thunderbolt  (USB-C) ports and four USB ports. Dual 4K displays or one 5K/6K/8K display, high-performance storage (including NVMe solutions), A/V mixers, phones or tablets, even desktop accessories like a keyboard or mouse are all fair game. Any accessories with past, present or future USB or Thunderbolt interfaces… all connect to the OWC Thunderbolt Dock. 
Expanded Connectivity via Enhanced Compatibility
When the latest Thunderbolt appeared on Macs and PCs, it used a USB-C connector to transfer data, output video, and charge devices through the same cable. The OWC Thunderbolt Docks Thunderbolt 4 ports use that same USB-C connector to create a multi-connectivity solution for millions of existing and future Thunderbolt computers and devices. Plus, the ports are fully USB4 future compatible.
Connectivity Reimagined 
Removing any device other than the last one in a daisy chain will break your chain and render all devices unusable until the chain is re-established. The OWC Thunderbolt Dock lets you create three separate tree branch chains, so you can remove devices from one chain without affecting or disconnecting the others. You can even add three Thunderbolt bus-powered devices for enhanced connectivity.
Unleash Drive Performance
In the past, daisy chaining external storage required you to place it close to the front of the chain to get fast, reliable performance. That wasnt possible with bus-powered drives. They had to be placed last in the Thunderbolt chain… and the chain was limited to just one bus-powered device! Now, you can connect multiple portable SSDs directly to the OWC Thunderbolt Dock to experience the fastest speed your storage device can deliver. 
Get Wired 
Nothing can put you behind schedule like slow, low-quality Wi-Fi. But you dont have to settle for a sub-par connection. Just plug the OWC Thunderbolt Docks Gigabit Ethernet port into a wired network for uninterrupted downloads, fast and reliable file transfers, secure network access, and increased productivity. The OWC Thunderbolt Docks Ethernet port facilitates collaboration and guards your precious data, so you can knock out that big team project… without worrying about your WiFi connection.
SD Card Reader
Getting content to your computer is a necessity now that photo and video creation have become part of daily life. Dont waste time struggling with data transport. Transfer your creative files quickly, easily, and conveniently with the OWC Thunderbolt Docks SD card reader. You can also use the reader like an external drive to store or backup files at will.
A Higher Vision
The OWC Thunderbolt Docks Thunderbolt technology let you connect to a single 5K/6K/8K display or two 4K displays. Enjoy more precise and vivid details in graphic-intensive CAD drawings. Attend a video meeting on one screen while editing content on another screen. Up your Photoshop or Affinity Photo images up a notch. Edit large format video on one display, while previewing the raw playback on the other. Whatever your workstation display needs, the OWC Thunderbolt Dock gives you the vision to take it to the next level.
Powerful Freedom
Gobs of charging power, so you can do it all: Keep your notebook ready for mobile use, power/charge your devices, and free up a Thunderbolt port on your machine… simultaneously. Ready to take a break or done for the day? The Thunderbolt and USB ports continue to power and/or charge connected devices.
Disconnect in One Click
OWC Dock Ejector software safely disconnects multiple drives connected to the OWC Thunderbolt Hub in a single click. Designed by OWC hardware and software engineers, Dock Ejector ensures all data is written before disconnection, saving time and protecting against data loss.
Secure Your Workflow with OWC ClingOn
Active workspaces expose gear to bumps, shoves, and the random tail wag from a pet. Just one ill-timed touch can cause an accidental cable disconnection interruption to your workflow. OWC ClingOn custom cable stabilizers (sold separately) screw into the OWC Thunderbolt Hub’s housing to secure your Thunderbolt (USB-C) connections so you can work with confidence even in the highest foot traffic environments.
