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 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 quite hit the official maximums of 7,000MB/s and 6,5000MB/s for reads and writes respectively. However, both the read result of 6,890MB/s and the 6,160MB/s for writes are the fastest we've seen to date for a consumer 1TB class drive.
