ATTO is one of the oldest hard drive benchmarks that is still used today. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that you can easily interpret. The test was run with the default runs of 0.5kb through 8192kb transfer sizes with the total length being 256mb.

Kingston DT Ultimate G2 32GB:
Benchmark Results: On the USB 3.0 header the Kingston Ultimate 3.0 64GB Flash Drive was able to run at 95MB/s read and 67MB/s write, which is well beyond the 80MB/s read and 60MB/s write ratings given to the drive first generation drive by Kingston. The second generation DataTraveler Ultimate 3.0 G2 32GB Flash Drive was able to reach 107MB/s read and 55MB/s write in ATTO. Just like we saw in CrystalDiskMark the new G2 drive doesn’t perform too well with very small file sizes, but starts to do better with files that are 64k and larger.
