Trade-offs

Strengths and limitations

Published together so the trade-offs are visible before you decide.

Strengths

  • Fifteen ports and a card reader that keeps up: The recorded port count is fifteen, with 5 USB-A at 5 Gb/s, 1 USB-C at 10 Gb/s at the rear and 1 USB-C at 5 Gb/s at the front, and the recorded card readers are SD 4.0 UHS-II at up to 312 MB/s. The port count and the card slot are what the box exists to provide.
  • Charges the laptop at up to 87 W while driving two displays: The recorded laptop charging is up to 87 W and the recorded display support is two displays at up to 4K 60 Hz each, or one display at up to 5K 60 Hz over Thunderbolt. One box handles the power and the picture for a Thunderbolt 3 laptop.
  • The smaller and lighter of the two CalDigit docks: The recorded weight is 0.47 kg and the recorded dimensions are 131 by 40 by 98.44 mm, against the TS4's recorded 0.64 kg and 141 by 42 by 113 mm. No price is recorded for either dock, so size and weight are the recorded differences between them.

Limitations

  • Thunderbolt 3, with a display limit on base Apple silicon: The recorded protocol is Thunderbolt 3, and the manufacturer states that Apple M1 and M2 laptops support only one external display through their Thunderbolt port while M1 Pro and M1 Max support two. On a base M1 or M2 Mac the recorded two-display support is not available.
  • It needs a socket and a 180 W adapter: The recorded power source is an external power supply with a 180 W adapter, so the dock is fixed to a desk and needs a socket and a cable of its own. A bus powered hub takes its power from the laptop and needs neither.

CalDigit TS4 Thunderbolt Station

Both expand a laptop, but the TS4 is a powered Thunderbolt dock with far more bandwidth, more ports and high-wattage charging, which is the reason to pay more.

FAQ

Common questions

What protocol does the CalDigit TS3 Plus use?

Thunderbolt 3 is the recorded protocol. The CalDigit TS4 in the catalogue records Thunderbolt 4 instead, and the catalogue holds no compatibility statement between the two protocols.
