How to pick the right USB-A hub
Question 1: how many ports? Mouse + keyboard + headset + USB stick = 4 ports. Plus webcam + printer + external drive + USB DAC = 7 ports. Question 2: do I need power supply (powered hub)? Mouse, keyboard, sticks = unpowered is fine. External HDD without own supply, USB DAC, printer = powered hub with PSU, because USB-A 3.0 only delivers 900 mA (4.5 W). Question 3: USB 2.0 or USB 3.0? USB 3.0 (5 Gbps) is the standard and covers 99 % of use cases. USB 2.0 hubs only make sense on the tightest budget — too slow for external SSDs.
