Corsair Voyager GS 128GB USB 3 flash drive

The next stage is to analyse the performance of the drives with some of the best software available online.

Crystalmark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s.

We tested the Corsair Voyager GS 128GB drive and the results are very positive indeed. We recorded around 289 MB/s sequential read and 181 MB/s sequential write. This is much greater than the claims on the Corsair webpage – although they are only using the ATTO Disk Benchmark.

Due to the nature of this kind of flash, and via the USB 3.0 interface, 4k and 4k QD32 performance is substantially worse than from a native SSD drive across a SATA connector.


Above, a few comparison results for reference.

The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage systems performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously. Use ATTO Disk Benchmark to test any manufacturers RAID controllers, storage controllers, host adapters, hard drives and SSD drives and notice that ATTO products will consistently provide the highest level of performance to your storage.

Results from the ATTO Disk Benchmark are not as impressive, and actually not reflective of real world results we achieved in the Windows 7 operating system earlier in the review. Sequential read speeds peaked at around 270 MB/s but the sequential write speed dropped to around 75 MB/s.

A few comparisons from other performance drives we have evaluated in recent months.
