what is the difference between usb 2.0 vs 3.0?
245348
When comparing 2.0 and 3.0 there are a few major differences. First the transfer rates: USB 2.0 offers transfer rates of 480 Mbps and USB 3.0 offers transfer rates of 4.8 Gbps - that's 10 times faster. Note that the transfer speeds also depend on the device in use in addition to the bus type and USB ports and cables.

USB 2.0 (High-speed USB) provides additional bandwidth for multimedia and storage applications and has a data transmission speed 40 times faster than USB 1.1.

USB 3.0 products address this demand with SuperSpeed data and video transfer rates 10x faster than current USB 2.0 technology. ... USB 3.0 docking stations provide full 1080p video to dual screens. The majority of OEM products only support one external monitor.

USB 3.1 is backwards compatible with USB 3.0 and USB 2.0, except in the following scenarios: USB-B 3.1 cables are not compatible with USB-B 2.0 ports. Unless you use an adapter, USB-C ports or cables will not work with USB-A or USB-B ports or cables.

USB 3.0 Type B plugs are larger than USB 2.0 (or earlier) Type-B plugs; therefore, USB 3.0 Type-B plugs cannot be inserted into USB 2.0 (or earlier) Type-B receptacles. Micro USB 3.0 (Micro-B) plug and receptacle are intended primarily for small portable devices such as smartphones, digital cameras and GPS devices.

USB 3.1 Gen 2 drives are backwards compatible with both USB 3.0/3.1 Gen 1 and USB 2.0 ports and connectors. Even when you use USB 3.1 drives on your USB 2.0 host devices, you'll still save time.

USB 3.1 Gen 1, originally known as USB 3.0, is capable of 5 Gbps transfer speeds—that's called SuperSpeed. USB 3.1 Gen 2 is capable of 10 Gbps transfer speeds—that's called SuperSpeed+. Technically, it accomplishes this by using 128b/132b encoding in a full-duplex communications mode.

USB 2.0 has 4 connector wires while USB 3.0 has a total of 9 connector wires. USB 2.0 offers a transfer rate of 480 Mbps and USB 3.0 offers speed up to 5 Gbit/s, which is 10 times faster. USB 2.0 devices are generally less expensive than USB 3.0 devices.

Thunderbolt 2 vs USB 3.0 vs eSATA: Speed All three standards are much, much faster than USB 2.0, which tops out at 480Mbps. eSATA can deliver 6Gbps (older versions deliver 1.5Gbps or 3Gbps), USB 3.0 runs at up to 5Gbps and the incoming USB 3.1 should do 10Gbps. Thunderbolt can do 20Gbps.

USB-C, USB 3.1, and Transfer Rates That's double the bandwidth—as fast as a first-generation Thunderbolt connector. USB Type-C isn't the same thing as USB 3.1, though. USB Type-C is just a connector shape, and the underlying technology could just be USB 2 or USB 3.0.

Check for any labels on your ports that are marked as 1.0, 1.1, 2.0, 3.0, or 3.1. The version number specifies how fast USB devices can transfer files. A USB port with just the USB symbol labeled is typically a USB 2.0 port. If the USB port has “SS” (or “SuperSpeed”) on its label, it's a USB 3.0 port.

USB 3.0 (aka USB 3) is a specific generation of USB ports. ... USB 3.0 ports have 9 pins and have a transfer rate of 5 Gbit/s, but 3.1 versions have 10 Gbit/s. While not technically a USB 3 port, the USB-C connector supports USB versions 3.1 and 3.2 and can connect to USB 3 ports with the correct cable or adapter.

A USB type C port may support USB 3.1, 3.0 or even USB 2.0. USB 3.1 Gen1 is just a fancy name for USB 3.0, which provides speed up to 5Gbps while USB 3.1 Gen 2 is another name for USB 3.1 which provides a speed of 10Gbps.

USB 3.1 is also known as USB 3.1 Gen 2 (10Gbps). USB 3.0 is capable of data transfer speeds up to 5Gbps. USB 3.0 is also known as USB 3.1 Gen 1 (5Gbps). ... Devices that require USB 3.1 transfer speeds of 10Gbps might not work with USB 3.0 or USB 2.0, or you might experience lower transfer speeds and impacted performance.
288096
USB 3.0 cables facilitate the faster transfer rates of 4.8Gbps as well as the additional power transfer of 900 mA by doubling the amount of wires within the cable from 4 in the 2.0 cables to 8 in the 3.0 cables. USB 2.0 cables transfer data at 480 Mbps and provide power up to 500 mA.
672640
USB 3.0 is capable of data transfer speeds up to 5Gbps. USB 3.0 is also known as USB 3.1 Gen 1 (5Gbps). USB 3.1 is backwards compatible with USB 3.0 and USB 2.0, except in the following scenarios: ... Bus-powered USB devices that requires more power than what USB 2.0 can provide are not compatible with USB 2.0.

It depends on the USB revision; whether we're talking about 3.0, 3.1 or 3.2. SATA 3 has a speed of 6 Gbit/s. So, if you're using USB 3.1 or higher, USB is faster.
