Why people pick it

  • 10Gbps (USB 3.2 Gen 2) on all four ports, with UASP, suited to fast external SSDs
  • Two USB-C and two USB-A ports, so both cable types plug in without adapters
  • Bus-powered with a 25cm attached cable; no power adapter to carry
  • Driver-free on Windows, macOS, Linux, iPadOS, ChromeOS and Android, and works in Thunderbolt 3 ports
  • Aluminum shell, 70g

Know before you buy

  • No video output: the USB-C ports do not support DisplayPort Alt Mode
  • No pass-through charging port, so it takes one of the laptop's USB-C ports for itself
  • Bus-powered: 4.5W per port and 15W total, depending on the host
  • All four ports share one 10Gbps link to the computer
  • The cable is attached, so it cannot be swapped for a longer one
