USB ports are something we all use, but few people truly understand what the symbols and labels on them mean. From cryptic “SS” markings to version numbers like USB 3.2 Gen 2×2, the world of USB has gotten a lot more confusing than it used to be. In this guide, we’re going to break it all down. Whether you’re shopping for a new laptop, building a PC, or just trying to figure out why your file transfer is so slow, understanding USB port types — especially SS 5, SS 10, and newer — will help you make smarter decisions.

What Does “SS” Mean on a USB Port?
“SS” stands for SuperSpeed, a term introduced with USB 3.0. When you see “SS” on a port, it’s shorthand for a USB port capable of faster data transfers than older USB 2.0 ports. The number following “SS” indicates the theoretical maximum transfer speed in gigabits per second (Gbps). For example:
- SS 5 = SuperSpeed USB at 5 Gbps (USB 3.0 / USB 3.1 Gen 1)
- SS 10 = SuperSpeed+ USB at 10 Gbps (USB 3.1 Gen 2)
- SS 20 = SuperSpeed+ USB at 20 Gbps (USB 3.2 Gen 2×2)
These numbers don’t just represent theoretical maximums; they also reflect practical differences in real-world performance depending on your device, cable, and port compatibility.
A Timeline of USB Speed Evolution
USB Version | Marketing Name | Symbol / Label | Max Speed | Year Introduced |
---|---|---|---|---|
USB 1.1 | Full Speed | — | 12 Mbps | 1998 |
USB 2.0 | Hi-Speed | — | 480 Mbps | 2000 |
USB 3.0 / 3.1 Gen 1 | SuperSpeed | SS | 5 Gbps | 2010 |
USB 3.1 Gen 2 | SuperSpeed+ | SS 10 | 10 Gbps | 2013 |
USB 3.2 Gen 2×2 | SuperSpeed+ | SS 20 | 20 Gbps | 2017 |
USB4 | — | USB4 | 40 Gbps | 2019 |
USB4 v2.0 (2024) | — | USB4 2.0 | 80–120 Gbps | 2024 |
The rebranding of USB versions (e.g., USB 3.0 becoming USB 3.1 Gen 1) has caused a lot of confusion. Many devices still use “SS” labels to indicate speed, which is why it’s important to look beyond just the port’s name and understand what it’s actually capable of.
Visual Clues: How to Identify USB Ports
When trying to tell USB ports apart, look for:
- Color Coding:
- Black = USB 2.0
- Blue = USB 3.0 / SS 5
- Teal = USB 3.1 / SS 10
- Red or Yellow = USB charging (may also support sleep-and-charge)
- Thunderbolt symbol = Thunderbolt-capable (can carry USB4, DisplayPort, PCIe)
- Symbols & Markings:
- A “SS” followed by a number indicates SuperSpeed USB.
- A battery icon next to a port means it supports USB Power Delivery or fast charging.
- Thunderbolt 3/4 ports often double as USB4 ports and use the USB-C shape.
USB-C vs USB-A vs USB-B: Shape Matters Too
Beyond speed, USB connectors come in different shapes:
- USB-A: The classic rectangular port, common on PCs and older accessories.
- USB-B: Often used with printers and older external hard drives.
- USB-C: Reversible, compact, and capable of delivering data, video, and power — it’s becoming the universal standard.
Importantly, USB-C doesn’t always mean high speed. A USB-C port could support USB 2.0, 3.0, 3.2, or even Thunderbolt — so always check the specs.
Real-World Use Cases: Why SS 10 vs SS 5 Matters
If you’re transferring large video files, editing off an external SSD, or using a VR headset, SS 10 or higher can make a significant difference. For example:
- Copying a 10GB 4K video file:
- Over SS 5 (5 Gbps): ~20–25 seconds
- Over SS 10 (10 Gbps): ~10–12 seconds
- Over SS 20 or USB4 (20–40 Gbps): ~5 seconds or less (depending on drive speed)
In contrast, using USB 2.0 for that same file would take several minutes. That’s why it pays to know your port.
Thunderbolt, USB4, and the Future
Intel’s Thunderbolt 3 and 4 use the USB-C connector and offer speeds of up to 40 Gbps, video output, and PCIe connectivity. USB4, which builds on Thunderbolt 3, can deliver similar performance — and newer versions like USB4 v2.0 will double those speeds to 80 Gbps (and possibly 120 Gbps with asymmetric transfer).
Many high-end laptops now feature Thunderbolt 4 ports that are backward compatible with USB-C and USB 3.2, making them incredibly versatile. This convergence points to a future where one port can truly do it all — power, video, data, and accessories — but only if you understand its capabilities.
How to Choose the Right USB Port for Your Needs
Here’s a quick cheat sheet:
Need | Recommended USB Type |
---|---|
Charging a phone | USB 2.0 or higher |
Transferring files (basic use) | SS 5 (USB 3.0 / 3.1 Gen 1) |
Editing video or large transfers | SS 10 or SS 20 |
Docking stations & displays | Thunderbolt 3/4 or USB4 |
Future-proofing | USB4 v2.0 / Thunderbolt 4 |
Final Tip: Don’t Skimp on Cables
Even if your port supports SS 10 or USB4, using a cheap cable can throttle your speeds. Always use certified cables that match your device’s capabilities. USB-C cables can vary widely — some are charge-only, others support high-speed data and video. If you’re getting slow speeds, your cable may be the bottleneck.
Understanding USB port types like SS 5, SS 10, and beyond isn’t just for techies — it’s for anyone who wants to get the most out of their gear. Knowing the difference can save you time, prevent frustration, and help you make better buying decisions. As USB4 v2.0 rolls out with lightning-fast speeds, keeping up with USB terminology will be more important than ever.
Best USB External Hard Drives
External hard drives provide extra storage space for important files, photos, and media. These portable devices connect to computers through USB, Thunderbolt, or other interfaces, allowing users to expand their storage capacity beyond built-in drives.
External hard drives come in various sizes and capacities, making them suitable for everyday backups, large media libraries, or professional data management.
The technology behind external drives has evolved significantly, with options now including traditional hard disk drives (HDDs) and solid-state drives (SSDs).
HDDs offer more storage per dollar but operate with moving parts. SSDs have no moving parts, operate silently, and provide faster data transfer rates, though they typically cost more per terabyte.
When shopping for an external hard drive, focus on storage capacity, connection type, and speed. Storage needs vary widely—from 1TB for basic document backup to 18TB or more for video editors or content creators.
The connection interface (USB 3.0, USB-C, Thunderbolt) affects both compatibility and transfer speeds. We also recommend considering portability, durability, and security features based on how you plan to use the drive.
We’ve compiled a comprehensive list of the top external hard drives available today. These devices offer reliable storage solutions for backing up important files or expanding your computer’s capacity.
Our selections balance storage space, transfer speeds, durability, and value to help you find the perfect external drive for your needs.

Buying Guide
Choosing an external hard drive requires careful consideration of several key factors. We recommend starting with storage capacity, as this determines how much data you can store.
Most users need at least 1TB for backups, while professionals working with video may need 4TB or more.
Connection type plays a crucial role in transfer speeds. Here’s what you should know:
Connection Types:
- USB 3.0/3.1/3.2 – Common and offers good speeds
- USB-C – Newer, faster, and becoming standard on modern devices
- Thunderbolt – Fastest option, but typically more expensive
Physical size matters if you plan to carry your drive. Portable drives are small enough to fit in a pocket, while desktop drives are larger but often offer more storage.
Durability Considerations
For those who travel, a rugged drive with shock resistance, water resistance, or drop protection can be worth the extra cost. These drives include protective bumpers and sealed cases to protect your data.
Transfer speed is important if you move large files regularly. Look at both the drive’s capabilities and the interface. SSDs are much faster than traditional HDDs but cost more per gigabyte.
Power source should be factored into your decision. Portable drives draw power from your computer’s USB port, while desktop drives require their own power supply.
Reliability Factors
Feature | Why It Matters |
---|---|
Warranty | Longer warranties often indicate better quality |
Brand reputation | Established brands typically offer better reliability |
Failure rate | Research average failure rates before purchasing |
Backup software often comes included with external drives.
We find this valuable for automating the backup process and ensuring data safety.
