What is USB 3.0?

What is USB 3.0?

USB 3.0 is the next major revision to the Universal Serial Bus (USB). It offers the same ease-of-use and plug and play capabilities as previous generations of USB technologies but with a 10X performance increase and better power management. For users of USB 3.0, the goal of connecting devices to PCs or notebooks is still the same as the USB 2.0 specification.

How fast is USB 3.0?

The performance increase is achieved through the USB 3.0 technology, which allows multiple streams of data transfer and boosts its peak signaling bandwidth to 5Gbp/s compared to 480Mbp/s on USB 2.0. Although the specifications are 5Gbps, transfer speeds vary based on the controller and NAND Flash configuration. Currently USB 3.0 drives can be found with various architecture and channels.

Why do you need that much speed?

USB 3.0 helps you save more time and USB 3.01 drive transfers files faster than USB 2.0 drives. Depending on the number of channels the transfer speeds and the type of files you transfer, USB 3.0 can save you a lot of time compared to standard USB 2.0 drives.

Will a USB 3.0 drive work on my device with USB 2.0 ports?

USB 3.0 devices are compatible with USB 2.0 and USB 1.1 ports and connectors but will only run at the host device performance. USB 3.0 devices will, however, help to maximize the throughput of USB 2.0 ports.

Why do I need a USB 3.0 drive when I use only USB 2.0 ports?

Due to the broad deployment of USB 2.0 devices in the market, USB 3.0 devices had to be backwards compatible. Even when you use USB 3.0 drives on your USB 2.0 host devices, you’ll save time.
