What the specs mean for you

Data speed

40 Gbps

Thunderbolt/USB4 class: fast NVMe SSDs, docks and high-res displays over one cable.

Total ports

1

Compact: the essentials for travel or a light setup.

Why people pick it

  • USB4 runs at full speed on Thunderbolt and USB4 Macs, which can't use 20Gbps USB 3.2 Gen 2x2 drives
  • Rated up to 3,800MB/s read, far beyond 10Gbps and 20Gbps USB drives
  • IP65 water resistance, 2m drop protection and a 5-year warranty

Know before you buy

  • Needs a USB4 or Thunderbolt 4 port for its rated speed; on USB 3.2 ports it drops to that port's speed
  • Only a USB-C to C cable in the box, no USB-A adapter
  • Larger and heavier than pocket drives (140mm long, 172g)
