Although, if you plug a USB 2.0 peripheral in a USB 3.0 port or plug a USB 3.0 peripheral into a USB 2.0 port, you can only transfer data at the USB 2.0 speed.The real 5 Gbit/s magic happens when you connect a USB 3.0 peripheral to a USB 3.0 port using a USB 3.0 cable. You can also plug a USB 3.0 peripheral into a USB 2.0 port and it will work just fine. USB 3.0 is also backward-compatible with USB 2.0, so you can plug a USB 2.0 peripheral into a USB 3.0 port and it will function properly. But USB 3.0 is 10 times faster than USB 2.0, with transfer rates of up to 5 Gbit/s. A later version, so dubbed USB 1.1, was released in 1998 and was designed to transfer data at a maximum theoretical rate of 12 Mbit/s. USB 2.0, introduced in 2000, is theoretically 40 times faster, with transfer rates up to 480 Mbit/s. USB 1.0, introduced way back in 1996, was designed to transfer data at a maximum theoretical rate of 1.5 Mbit/s. You can do it for a minimum of around $20.
If you’re stuck with USB 2.0 for the foreseeable future, you might want to add USB 3.0 connectivity to your current platform. In fact, many new computers sold today still feature USB 2.0 only. Most users are stuck with USB 2.0 until they buy a new computer, even if the computer they have is relatively new. Unfortunately, most computers in use today don’t have integrated USB 3.0 ports. USB 3.0 peripherals are proliferating, with lots of affordably priced external hard drives, Blu-ray burners and other devices to choose from. USB 3.0 is about 10 times faster than USB 2.0, making it a terrific upgrade, and a great way to save time by cutting down on file transfer times.
