Thunderbolt 3: One Connector for Everything

What is Thunderbolt 3?

Thunderbolt 3 allows for high-speed performances for USB-C enclosures that utilize Thunderbolt 3 ports. Thunderbolt 3 is often advertised for being capable of transferring data at 40 Gbps. But, a good portion of that is set aside for managing video. It is often the case that the full 40 Gbps is not being consumed. The actual maximum amount of data transfer allowed by Thunderbolt 3 is 22 Gbps, which is 2750 MBps. 


  • High Speeds
    • Up to 22 Gbps of data delivery (2750 MBps)
    • Up to 40 Gbps of Display Port and USB Multi-function
  • Multi-functional
    • Data
      • Delivers data at high-performing speeds for storage and adapters
      • Power
        • Charging up to 100 W
        • Supplying up to 15 W to bus-powered devices (storages, displays, adapters)
      • Media
        • Produce advanced video and audio quality (4k60Hz displays)
      • Networking
        • Virtualize an Ethernet adapter to transfer traffic from the host system over the PCI Express interface
    • Integration of Multiple Protocols
      • USB 2.0, 3.0, and 3.1
      • Thunderbolt
      • Display Port
      • PCI Express
    • Small form factor
      • Integration of multiple protocols also integrates numerous cables into one connector

    Why Shell Thunder?

    The market is filled with many other USB-C enclosures that work with Thunderbolt 3. However, the problem is that almost none of them are capable of taking advantage of the high speeds that Thunderbolt 3 supports. Shell Thunder allows for speeds that can almost reach 2500 MBps.

    Shell Thunder is engineered with smart fan technology for active cooling, and also comes with a thermal cooling pad for additional passive cooling. This allows for Shell Thunder to support lightning speeds, testing at 2,498 MB/S Read and 2,309 MB/S Write.
