We ran HD Tach v220.127.116.11 and selected the Full Bench test, which puts the USB stick through a more thorough testing procedure:
The full bench test scans the entire capacity of the module and graphs the average reading and writing performance:
The performance of OCZ ATV Turbo is close to the specs, with 33MB/sec reading and 25MB/sec writing. This can be considered as quite good, especially when compared with other popular USB sticks.
The OCZ ATV Turbo is only to the Lexar JumpDrive Lightning, in reading performance, while it is the fastest in the writing benchmark.
