USB 2.0[edit] The Hi-Speed USB Logo A USB 2.0 PCI expansion card USB 2.0 was released in April 2000, adding a higher maximum signaling rate of 480 Mbit/s (High Speed or High Bandwidth), in addition to the USB 1.x Full Speed signaling rate of 12 Mbit/s. Due to bus access constraints, the effective throughput of the High Speed signaling rate is limited to 280 Mbit /s or 35 MB/s.[26] 3刀以下可以买3.0的了 还买2.0干嘛
