NOTE: ThundOrigin is compatible with the latest USB 4.0 interface.

ThundOrigin is a big step for the USB external hard drive.

Before Thunderbolt 3, the fastest speed for USB external hard drive is 10Gbps (USB 3.1 Gen2). Now, with Thunderbolt 3, ThundOrigin provides Max. 40Gbps speed for an external hard drive. You can run an operating system on an external hard drive; the speed is the same or even faster than the internal hard drive.

NVMe SSD generates massive heat when working, so we enhanced the cooling system on ThundOrigin:

  1. SSD heat sink and thermal pad rapidly radiate heat from internal SSD to external Aluminum enclosure
  2. A separate heat sink for the Thunderbolt 3 main chip
  3. Aluminum case with heat exchange fins, practically enlarge the heat dissipation area

Just because the high-efficiency of heat transfer, after heavy load using, the Aluminum case may become hot, this is correctly helping internal SSD cooling down.

Besides, we included a silicon rubber bumper for shock-absorbing and heat insulation.
