USB 3.0 vs USB 2.0 read write Review & Benchmarks speed Test
Lets have a small briefing, features and specifications about the new generation of USB, Then some selection of best reviewers.
The USB 3.0:

Features:
* A new major feature is the SuperSpeed bus, which provides a fourth transfer mode at 4.8 Gbit/s. The raw throughput is 4 Gbit/s, and the specification considers it reasonable to achieve 3.2 Gbit/s (0.4 GByte/s or 400 MByte/s) or more after protocol overhead.

USB 3.0 vs USB 2.0 Super Talent Benchmarks Test :
MacBook USB performance:
On the new Retina MacBook pro USB 3.0Vs the old 2011 MacBook pro USB2.0, performance diference is huge (by anandtech).
USB 2.0 Vs USB 3.0 ATTO Benchmark result :
Using ASUS TUF X58 SABERTOOTH motherboard and 7,200 RPM internal drive, (by bjorn3d)

Why USB 3.0 is only around 150MB/s speed:
Because of the CRC check on the two ends, the final performance result of the USB 3.0 is not as we expect, take look at the Theoretical table bellow:
Interface | Data Rate (Bits/s) | Theoretical Bandwidth (Bytes/s) | Theoretical Bandwidth After 8b/10b Encoding (Bytes/s) |
---|---|---|---|
USB 2.0 | 480Mb/s | 60MB/s | 48MB/s |
USB 3.0 | 5Gb/s | 625MB/s | 500MB/s |
