It wont be long before USB 3.0 takes over USB 2.0 specification
The original USB specification was introduced in 1996, however, it wasn’t until two years later and v1.1 that it became a widely accepted standard. Its speed was 12Mbps which was good enough for its time but slowly and gradually, USB drives and peripherals started gaining market share and along with the introduction of Firewire, USB suddenly felt ultra-slow. Thus, USB2 was released in 2001 increasing the speed of USB to a whopping forty times at 480Mbps.
Its time to revise this standard as well as you must have seen the limitations of bandwidth that USB2.0 offers in our Flash and Hard Drive tests of late that pretty much saturate the bus. Although USB 3.0 doesn’t offer a fortyfold speed increase from USB 2.0, it still offers a pretty decent jump at ten times the speed of the bus its succeeding. At 4.8Gbps or approximately 570 MB/s, USB 3.0 should satisfy most of the peripherals connected to it.
