The latest of these standards, USB 3.2 was released in September 2017. Also called SuperSpeed+, USB 3.1 has a theoretical speed of 10 Gbps. In 2013, its successor, USB 3.1 was released. In recent years, much faster USB standards were introduced. However, to ensure the fastest transmit rate possible, both devices that you want to connect should have support for USB 3.0. But USB 2.0 Micro-A plugs are compatible with USB 3.0 Micro-AB receptacles.

They are compatible with Micro-A receptacles and are also used for smartphones and small portable devices. These look like the USB Micro-A type, with the thin and two-part design.

If you want to know more about how to charge your phone faster, check out our previous blog here.
While USB 2.0 caps out at around 0.5 Amps, a USB 3.0 charger can deliver around 0.9 A of power. In fact, a USB 3.0 charger can deliver almost double the output of a USB 2.0 charger. You can also charge your devices faster with a USB 3.0 connection.
That means USB 3.0 is 225% faster vs USB 2.0 for transferring files. With USB 3.0, it would only take roughly 87 seconds to transfer the same file. That means it would take around 282 seconds (or almost five minutes) to transfer a 10GB file.
Real-world tests show that USB 2.0 can transfer files at a speed of 35.4 Mbps (megabits per second). That may not sound fast, but it’s actually 10 times faster than USB 2.0. That’s roughly 87 seconds (or about a minute and a half). According to a test conducted by Macworld, a 10GB file can be transferred to a hard drive using USB 3.0 at 114.2 Mbps. In real-world tests, USB 3.0 transfers files much slower than its theoretical speeds.

This means an HD movie around 1.5GB in size can be transferred from one device to another in less than a second using it (theoretically).

Be sure to know what the ports on your Mac are if you have one.USB 3.0 comes with a theoretical transfer speed of 5 gigabytes per second (Gbps). For example, the discontinued 12-inch MacBook had a USB-C port that wasn't Thunderbolt-equipped. However, like the USB 3 standard, not all USB-C cables and ports support Thunderbolt 3 or 4. Thunderbolt 3 is capable of transfer speeds up to 5GB/second. Starting with the Thunderbolt 3 standard, it now uses the USB-C connector. This is an interface developed by Intel and Apple that allows for much faster connections when transferring data. While we're discussing USB standards, it's important to also mention Thunderbolt. And keep in mind that these transfer rates are all theoretical maximums the real-world speeds probably won't reach those heights. You'll just be limited to the slowest speed supported by either device or the cable. These standards are all backward-compatible, so if you plug a USB 3.2 Gen 2x2 cable into a USB 3.0 slot, it will work fine. Marketers like to use general terms like "USB 3.2" without specifying the generation, so make sure you know what you're actually getting. But this standard is still in its early stages, and is thus not widely available at the time of writing.īecause of these overlapping terms that are easy to confuse, it's important to check the specific details on a cable (or device) before you buy it. Looking forward, USB 4 was released in 2019 and only works with USB-C connectors.
