Differences Between USB 3.0 and USB 2.0
The key differences between USB 3.0 and USB 2.0 are:
- USB 3.0 has 5 Gb/s full-duplex point to point transfer speed compared to 480Mb/s half-duplex broadcast for USB 2.0. This is nearly ten times the performance increase of USB 2.0.
- USB 3.0 increased power savings by optimizing power efficiency through no device polling and lower active and idle power.
| Note | USB 3.0 is backward compatible with USB 2.0 |
