ATTO Disk Benchmark
The ATTO Disk Benchmark program is free, and offers a comprehensive set of test variables to work with. In terms of disk performance, it measures interface transfer rates at various intervals for a user-specified length and then reports read and write speeds for these spot-tests. There are some minor improvements made to the 2.46 version of the program that allow for test lengths up to 2GB, but all of our benchmarks are conducted with 256MB total length. ATTO Disk Benchmark requires that an active partition be set on the drive being tested. Please consider the results displayed by this benchmark to be basic bandwidth speed performance indicators.
512GB OCZ RD400 ATTO Benchmark Results
The results obtained with the Toshiba driver (very) narrowly edge out the results obtained with the Windows 10 native driver. In either case the results are at the very top of the single-drive performance rankings.
This chart shows the difference in performance between SATA and m.2 SSDs very well: note that the SATA SSDs all bump up against the SATA bandwidth limit, while the m.2 SSDs provide up to five times the performance.
