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. The first shows the results for the Apex SSD:
The next result is for the G.Skill Titan:
By comparing these two, you can actually see that the Apex performed a little better in reads up and down the graph. I ran this a number of times on each drive and the results were consistent. Again, the Apex shows that it will run at the specified speeds with consistency.
