USB: Cables, hubs, and Thunderbolt

USB is quite complicated these days.

• USB-A is the connector you’re used to
• USB-C is the new connector
• Most ports support USB Protocol 2.0
• Some support USB 3.0 and have a blue block or ss
• Thunderbolt is something Intel and Apple made which supports more advanced uses of USB

USB-C

The connector is reversible. It also support higher power transfer.

What cable you get matters.

It’s possible to get a cheap, low-power USB-C cable which just charges your device slowly or provide slow data transfer.

You can also find cables which support extremely high data transfer or power.

Thunderbolt and USB4

USB4 supports all features of Thunderbolt 3. There is also now Thunderbolt 4 which supports even more things.

The best cables to buy are Thunderbolt 4 cables since they support all the previous features and also the new ones which require new devices which support Thunderbolt 4
