As an avid tech enthusiast and data analyst, I‘m always exploring the latest advancements in computer accessories and peripherals. And one key evolution I‘ve watched over the years is the continuous progression of USB technology standards.
From my early days tinkering with USB 1.1 cables in the late 90s to testing bleeding-edge USB4 gear today, I‘ve become obsessed with staying on top of each new USB generation and what it means for real-world performance.
So in this guide, I want to share with you my accumulated knowledge about what the different USB port and connector colors signify. More specifically, I‘ll answer the question – what does a purple USB port mean?
You‘ll learn how purple fits into the broader USB color coding system, along with some pro tips for achieving maximum speeds from your USB devices. I‘ll also recommend specific cables that I personally rely on for blazing fast 40Gbps transfers.
Let‘s dive in!
A Brief History of USB Evolution
It all started in 1996 with the release of USB 1.0, capable of pokey transfer rates up to 12Mbps. But successive USB versions continuously cranked up the speed:
- USB 1.1 (1998) – 12Mbps
- USB 2.0 (2000) – 480Mbps
- USB 3.0 (2008) – 5Gbps
- USB 3.1 Gen 2 (2013) – 10Gbps
- USB 3.2 (2017) – 20Gbps
- USB4 (2019) – 40Gbps
With each generational upgrade to the USB spec, the connectors and ports also evolved. This led to the familiar, colorful USB port identification system we rely on today.
For example, when USB 3.0 first hit the scene in 2008, the ports were colored blue to distinguish them from the original USB 1.1 and USB 2.0 versions.
But as newer, faster USB 3.x iterations were introduced, additional colors came into play, like teal for USB 3.1 and red for USB 3.2.
So when you spot a purple USB port, what does it mean? Let‘s examine the USB color coding scheme in more detail.
USB Port Colors and Corresponding Speeds
These days, you can easily spot the USB generation just by looking at port color. Here‘s a breakdown of what each USB port color represents in terms of speed:
- Black – USB 2.0 – 480Mbps
- Blue – USB 3.0 – 5Gbps
- Teal – USB 3.1 Gen 2 – 10Gbps
- Red – USB 3.2 Gen 2×2 – 20Gbps
- Green – USB 3.2 Gen 2×1 – 10Gbps
- Purple – USB 3.1 – 10Gbps
- Yellow/Orange – Charging Port – Power only
- White – USB 2.0 – 480Mbps
Now let‘s get specific about the meaning of purple USB ports.
Purple USB Ports – What Does This Color Signify?
You‘ll typically spot purple used on the connectors of USB cables and chargers rather than on host device ports. However, some manufacturers do implement purple USB 3.1 ports.
In either case, the purple color denotes support for the USB 3.1 specification, which permits data transfer speeds up to 10Gbps.
For example, you may see purple utilized on USB-C to Lightning cables for iPhones to indicate USB 3.1 Gen 2 capabilities. The purple essentially signals that the cable is optimized for high-speed 10Gbps data syncing.
And when USB 3.1 first launched back in 2013, some cable makers elected to use purple ends to distinguish these cables from the earlier, slower USB 3.0 versions coded in blue.
So in summary:
-
A purple USB port demonstrates the port or connected device is compliant with SuperSpeed USB 3.1 and its 10Gbps transfer rate.
-
Purple USB connectors or cables support the USB 3.1 Gen 2 standard for peak transfer speeds up to 10Gbps.
Now for some pro tips on achieving those blazing fast USB 3.1 speeds…
Pro Tips: Unlock 10Gbps+ Speeds from USB 3.1 Ports
Simply having a USB 3.1 purple port isn‘t enough. You need the right cable and host device setup to actually attain USB 3.1‘s peak 10Gbps data transfer rates.
Follow these expert recommendations when connecting USB 3.1 gear:
- Use cables with thicker, high-quality copper wiring – 22 AWG or lower. Thinner cables can‘t handle 10Gbps signals over longer cable runs.
- Go with shielded USB cables for protecting against EMI interference.
- For cable lengths over 3 meters, use active cables with integrated signal boosters. This maintains 10Gbps speeds over longer distances.
- Ensure the USB host controller and drivers support USB 3.1 Gen 2 for 10Gbps operation.
- Match high-speed cables to USB 3.1 compliant devices. Always verify specs before purchasing cables or peripherals.
- Consider using USB Type-C connectors for maximum compatibility and ease-of-use.
Adhering to those expert tips will prevent you from leaving USB 3.1 performance on the table. You paid for 10Gbps ports and cables – so follow best practices to achieve those quoted speeds!
Next I‘ll recommend some of my favorite USB 3.1 cables that I rely on for blistering fast data transfer and charging.
My Go-To Cables for USB 3.1 Speeds
Based on extensive real-world testing, these are the USB 3.1 cables that I recommend for maxing out the 10Gbps speed:
