We fired up HD Tach v3.0.1.0 and prepared the full length test, which examines the whole 8GB of memory:

The test takes some time to complete, don't forget this is an 8GB USB flash memory stick. But finally, we got our reading and writing graphs:

First of all the performance is very good. The reading performance is stable at 24MB/sec, while writing stays at 10MB/sec. The Random access time is only 1ms.

But how does this performance compare with other tested 8GB USB sticks?

Looking at the test results, we see that Corsair's Voyager GT 8GB is the fastest 8GB USB stick we have tested with 24MB/s average read speed and a very impressive 22.5 MB/s write speed. The OCZ 8GB Megacart has good reading speed but rather low writing performance. All three devices have very similar reading speeds, but it is the writing speed which makes the difference. At 10MB/s, the OCZ Rally 2 is good, but this is far behind the speed of 22.5MB/s offered by the Corsair Voyager.
