Selecting a USB hub involves considering your current and future needs for connecting devices to your computer.
Choosing the right USB hub primarily depends on the types of devices you want to connect and how many ports you need.
Key Considerations for Choosing a USB Hub
Here are the most important factors to think about when selecting a USB hub:
USB Speed and Compatibility
Matching the hub's USB version to your devices is crucial for optimal performance.
As highlighted, if you have multiple USB 3.0 or USB 3.1 devices, it's best to go for a USB 3.x hub to take advantage of faster transfer speeds. These hubs are backward compatible, meaning they will also work with older USB 2.0 or 1.1 devices, though the speed will be limited to the device's maximum speed. But if you only have USB 2.0 devices, a USB 2.0 hub will suffice, and these are often less expensive.
- USB 3.x (USB 3.0, 3.1, 3.2): Offers much faster speeds (up to 5Gbps for USB 3.0/3.1 Gen 1, 10Gbps for USB 3.1 Gen 2/3.2 Gen 2x1, etc.) suitable for high-speed devices like external hard drives, SSDs, and high-resolution webcams.
- USB 2.0: Offers slower speeds (up to 480Mbps), sufficient for keyboards, mice, printers, scanners, and USB flash drives.
Number of Ports Required
Think about how many USB devices you need to connect simultaneously. It's often wise to get a hub with one or two more ports than you currently need to allow for future expansion.
- Common port counts range from 3 or 4 up to 10 or more.
Power Source: Powered vs. Unpowered Hubs
USB hubs can either draw all their power from the host computer's USB port (unpowered) or come with an external power adapter (powered). This is a critical distinction.
Feature | Unpowered USB Hub | Powered USB Hub |
---|---|---|
Power Source | Draws power only from the host computer's USB port | Has an external power adapter or gets power in addition from the host |
Power Delivery | Limited total power; suitable for low-power devices (keyboards, mice, flash drives, low-power peripherals) | Can supply significantly more power; essential for high-power devices (external hard drives, charging phones, tablets, some webcams) |
Device Support | May struggle or fail when multiple high-power devices are connected simultaneously | Can reliably support multiple high-power devices simultaneously without performance issues or connection drops |
Port Count | Typically fewer ports (often 4 or less) | Can have more ports (often 4-10+) |
Performance | Performance may degrade when many devices are active simultaneously | Generally maintains better performance under heavy load |
Portability | More portable, no extra cable/adapter | Less portable due to external power supply |
- Choose a powered hub if you plan to connect devices like external hard drives, charge devices, or use multiple high-power peripherals.
- Choose an unpowered hub for connecting only low-power devices like mice, keyboards, or flash drives, especially if portability is important.
Port Types (USB-A, USB-C)
Consider the physical type of USB connector on your computer and your devices.
- Do you need standard rectangular USB-A ports, or the newer, smaller oval USB-C ports?
- Some hubs offer a mix of both port types. Ensure the hub's connector matches your computer's port (e.g., a USB-C hub to connect to a USB-C port on your laptop).
Form Factor and Additional Features
Consider the physical size and shape of the hub and where it will be placed.
- Compact/Travel hubs are small and portable.
- Desktop hubs might be larger with a power adapter and more ports, often designed to sit on a desk.
- Some hubs include extra features like Ethernet ports, SD card readers, or even video outputs (these are often referred to as "docking stations" but can function as hubs with added capabilities).
By evaluating these factors based on your specific setup and needs, you can select a USB hub that provides the right connectivity, speed, and power for your devices.
