The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage system 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 manufacturer's 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.
We are using version 4.1 for our NVMe disk tests.
Using the ATTO benchmark we couldn't get close to the official maximum read figure of 10,000MB/s with a test result of 8,890MB/s. The write test result was much closer to the official 10,000MB/s at 9,500MB/s.
Using the ATTO benchmark, the Legend 970 write performance peaked at the 128KB mark at 9.530MB/s and plateaued around that point for the rest of the test up to an I/O size of 8MB. The read performance levelled off between the 256KB and 512KB points before dropping from 8,690MB/s (512KB) to 8.150MB/s (1MB) before recovering quickly to peak at 9,380MB/s at 4MB and then staying at that speed until the 8MB mark.
