- Jun 04, 2018 -
Most laptops come with a USB 2.0 port, but that will change as their successor, USB 3.0, begins to change. Hewlett-Packard says it will bring USB 3. 0 to most of its high-performance and business laptops later this year.
The USB port connects host devices, such as PCs, to other devices, such as printers and storage drives. USB implementers forum USB-IFA USB3.0, which defines the USB standard, increases bandwidth and transfers data nearly 10 times faster than USB 2.0.
The USB 3.0 interface provides a transmission rate of 5 gigabits per second (bits per second), while USB 2.0 provides 480 megabytes of bps per second. For example, using USB 3.0 can transfer 1 gigabyte of data to a host device in 3.3 seconds, while using USB 2.0 takes 33 seconds.
With the development of USB 3. 0 technology, the transmission rate of drive will increase. Over the past few months, companies such as OCZ Super Talent and LaCie have seen external hard drives and storage devices such as SSDs with different rates of data transfer on their shelves.
